Abstract

Abstract: A new method for ARM detection and identification based on RAT(Radon-Ambiguity Transform) is proposed, by which no multichannel phase compensation preprocessing for missile acceleration is required. The detection of ARM signal is accomplished by one-dimensional searching and hence the computation is greatly reduced. Meanwhile the chirp rate identification is more accurate. Computer simulation shows that an accurate and reliable detection and identification of weak ARM signals can be achieved in the SNR environment as low as -10dB.

Key words: ARM, Radon-Ambiguity transform, multichannel phase compensation preprocessing

CLC Number:
