摘要：
LPI radar is a special kind of radar which incorporates some features and techniques to avoid being detected. Because of their advantages, FMCW waveform is often used in LPI emitters. In this work, an original method based on hidden Markov model is suggested for the detection of FMCW. The suggested method is composed of learning and decoding layers. As a result of the simulations, it is observed that several simultaneous LPI emitters having low SNR can be detected in a wide dynamic range.
