This report presents the results of IDA's study and analysis of the beacon collision avoidance system (BCAS) design proposed by The MITRE Corporation. This system, referred to herein as MCAS, is an active collision avoidance system which makes use of air traffic control radar beacon system (ATCRBS) transponders already possessed by a large fraction of the flying aircraft population. It is also compatible with the discrete address beacon system (DABS) in anticipation of that system's eventual adoption in place of ATCRBS. MCAS derives the same economic benefits accruing to any BCAS by virtue of relying on the use of ATCRBS transponders already installed in many aircraft. However, because the system is active, its design must assume, in principle, that airborne MCAS interrogator equipment will be limited to about ten percent of the flying population in order to avoid excessive garble for its own purposes and interference with regular ATCRBS ground stations. MCAS uses essentially the same threat logic for encounters between MCASequipped aircraft which was recommended by ANTC117 and its performance will therefore suffer the same deficiencies resulting from the use of that logic as predicted in previous IDA studies. These deficiencies are a high natural alarm rate due to a lack of certain parameter data, such as bearing rate and relative acceleration, and/or less than safe alarm criteria resulting from tradeoffs intended to reduce the alarm rate. For encounters with ATCRBS transponder equipped aircraft, MITRE has designed a special, socalled remitter logic, which has similar deficiencies

A Numerical Technique for the Calculation of Dispersion Relations and Mode Functions for Upper Ocean Internal Waves by Irvin W Kay (

This paper is concerned with calculating the internal wave eigenfunctions and dispersion relations for an infinitely deep ocean with an arbitrary Vaisala frequency profile. The method involves numerically integrating the differential equation from a depth where the profile is essentially an exponential function, and therefore where the eigenfunctions are known explicitly, to the surface where each eigenfunction must vanish. The equation that is implied by the surface boundary condition determines the dispersion relation, which is obtained numerically by solving the equation by means of the method of regula falsi. A computer program that performs the necessary calculations is described and listed
A Review and Analysis of the RCA Collision Avoidance System  Phase II

The study is an analysis of how well RCA's aircraft collision avoidance systems, known as the SECANT VECAS and the SECANT VECASGA, will perform in the highdensity traffic forecast for the Los Angeles Basin in 1982. The evaluation is based on the threat logic of ANTC117. The RCA equipment, consisting of reasonable assumed mix of VECAS, VECASGA, and a proximity warning indicator in its present design configurations, meets the relevant specifications and otherwise conforms to the intent of ANTC117. Some minor difficulties remain, the most significant of which is the possible delay in tracking one of two targets with nearly the same range. However, these are not expected to cause any serious design problems. Also, VECASGA should be provided with 32 rather than 16 trackers for operation in highdensity traffic. The system now appears to have some growth potential, and further improvements, leading to performance somewhat beyond that required by ANTC117, seem possible

On the Feasibility of Using Extremely Low Frequency Electromagnetic Fields to Detect Mines in Shallow Water

This document considers an approach to mine detection based on electromagnetic detection. It involves the use of a magnetic or electric dipole antenna to transmit a low frequency signal that would illuminate and interact with an object, such as a mine, all dimensions of which are small compared to the wavelength as well as to the distance between the object and the antenna. A dipole antenna, which may be the same as or different from the transmitter, would receive the signal due to the interaction of the illuminated body with the incident electromagnetic field. Past analyses have demonstrated the feasibility, even at fairly long ranges, of using bluegreen lasers to detect bodies immersed in pure water. Unfortunately, this detection method fails in turbid water, which is not transparent to the short wavelength laser radiation, and in cases where the mines have become buried. Sonar techniques, while useful in deeper water, also have problems in the shallow water regime because of clutter and reverberations

A concrete form for the mathematical theory of an inverse scattering problem is presented which was originally formulated in quantum mechanical terms. The problem is related to determining the variation of electron density in an ionized gas such as the earth's ionosphere by means of radio sounding experiment s he definitions and proofs of theorems have been revised in an attempt to take the analysis understandable to a reader we may not be familiar with the terminology of quantum mechanics or of the associated HILBERT SPACE THEORY. While the usual terminology employed by physicist has not been discarded completely, definitions and relations are given in concrete terms whenever possible, and abstract relations reused for convenience of notation rather than for the purpose of obtaining great generality. The physical problem at which the present work is aimed is to find the variation of electron density in a weakly ionized gas from a knowledge of the scattering amplitude resulting from the incidence of a plane electromagnetic wave. It is assumed that the relevant properties of the medium vary slowly enough so that a scalar wave describes the scattering phenomena with sufficient accuracy. it is also assumed that losses, ordinarily attributed to the collisions of the electrons with heavy particles may be neglected. The effect of an external magnetic field which would cause anisotropy is neglected as well, so that the scattering is assumed to be isotropic as well as losses

At infraredoptical frequencies the Edlen formula determines the index of refraction profile in a continuous, spherically symmetric atmosphere in terms of the pressure and temperature. Since the pressure dependence is known in terms of the temperature when equilibrium exists, a given temperature profile determines that of the index of refraction. The classical equation for rays propagating in such a medium then provides various geometrical properties of a ray, given its nearest minimum or maximum height relative to a specified viewing eye through which it passes. For altitudes above the surface of the Earth that are small compared to its radius the propagation geometry can be approximated in terms of a plane stratified medium above a flat ground surface. However, for distances large enough to include a horizon ray, a single corresponding approximate index of refraction profile is only valid for predicting the behavior of nearby rays. The slope of the index of refraction profile as well as that of the temperature determine the sign of the curvature of any ray at any height. Using the relationship between geometrical properties of the index of refraction profile it is possible to draw qualitative conclusions about the nature of possible mirages

The problem of evaluating numerically the DebyePicht Luneberg electromagnetic diffraction integrals in the short wavelength limit was investigated, and the method of stationary phase for evaluating these integrals was generalized for application to caustic regions. A test problem, involving the diffraction of a plane wave by a perfectly conducting paraboloidal reflector, was considered in this investigation. Results of sample calculations illustrating the techniques evolved are discussed. (Author)
A MidAir Collision Threat Algorithm That Uses Bearing Data

This paper derives an algorithm for use by an airborne midair collision avoidance system to determine when an alarm should be given in case a midair collision is imminent. The algorithm is based on an extension of the standard modified tau alarm criterion used in most collision avoidance system threat logics. The standard criterion uses only altitude and range data and, as a result, will generate high alarm rates in heavy air traffic. The criterion presented here makes use of bearing data as well as altitude and range data and should, therefore, provide lower alarm rates. (Author)
