Deinterleaving Radar Pulse Trains Using Neural Networks

نویسنده

چکیده

All known time of arrival (TOA) deinterleaving algorithms have great diiculty separating interleaved radar pulse trains when two or more of the trains are significantly jittered. Such scenarios tend to lead to overwhelming ambiguity and fragmentation diiculties when using traditional techniques. In this report we propose a modiied sequence search technique combined with a novel recursive neural network approach. The sequence search forms the hypothesis that a given chain of pulses is periodic and the neural network is used to intelligently test this hypothesis. This allows the satisfactory dein-terleaving of multiple jittered radar pulse trains.

Radar Pulse Train Parameter Estimation and Tracking using Neural Networks

The post-deinterleaving radar pulse train problem requires estimation of the parameters and tracking of the individual pulse trains. A simple recurrent back-propagation neural network is used based on a simple state space time series formulation of the radar problem. The network incorporates a novel hueristic adap-tive error threshold that allows simultaneously good tracking and parameter estim...

A New Algorithm for the Deinterleaving of Radar Pulses

This paper presents a new algorithm for the deinterleaving of radar signals, based on the direction of arrival (DOA), carrier frequency (RF), and time of arrival (TOA). The algorithm is applied to classic (constant), jitter, staggered, and dwell switch pulse repetition interval (PRI) signals. This algorithm consists of two stages. In the first stage, a Kohonen neural network clusters the receiv...

The limits of extended Kalman filtering for pulse train deinterleaving

Some signals, such as in radar systems, communication systems, and neural systems, are transmitted as periodic pulse trains. If more than one pulse train is transmitted over the same communication channel, a challenge is to separate them for source identification at the receiver. This is known as pulse train deinterleaving and is clearly a fundamental problem in the study of discrete-event syst...

Deinterleaving pulse trains in unconventional circumstances using multiple hypothesis tracking algorithm

The main function of Electronic Support Measure (ESM) is to receive, measure and deinterleave pulses, and then identify alternative threat emitters. Among these processes, pulse deinterleaving is vitally important because dense electromagnetic environments could cause an ESM system to receive a seemingly random pulse stream consisting of interleaved pulse trains with high noise levels. Only whe...
