Abstract:
Combining the mutual information theory and the sequential hypothesis testing （SHT） method， a self-adapting radio frequency （RF） stealth signal design method is proposed. The channel information is gained through the radar echo and feeds back to the radar system， and then the radar system adaptively designs the transmission waveform. So the close-loop system is formed. The correlations between these transmission waveforms are decreased because of the adaptive change of these transmission waveforms， and the number of illuminations is reduced for adopting the SHT， which lowers the transmission power of the radar system. The radar system using the new method possesses the RF stealth performance. Aiming at the application of radar automatic target recognition （RATR）， experimental simulations show the effectiveness and feasibility of the proposed method.
