Abstract

Abstract:

Combined with the optimum transmit-receiver (OTR) method and the sequential hypothesis testing (SHT) method, a new signal design method is proposed to improve the radar radio frequency (RF) stealth performance. The channel information is gained through the transmission waveform and fed back to the radar system, and the radar system adaptively designs the transmission waveform according to the channel information. It is a closed-loop system. The correlations between transmission waveforms are decreased because of the change of these transmission waveforms, and the number of illuminations is reduced for adopting the sequential hypothesis testing which lowers the transmission power of the radar system. The radar system using the new method possesses the radio frequency stealth performance. The simulation results of the target recognition application show the validity and feasibility of the method.

Key words: radio frequency stealth, optimum transmit-receiver, sequential hypothesis testing, adaptive design, closed-loop system
