Waveform Recognition in Pulse Compression Radar Systems [PDF]
2005 IEEE Workshop on Machine Learning for Signal Processing, 2006 In this paper a system for recognizing pulse compression radar waveforms is introduced. The waveforms considered in this study are the linear frequency modulation (LFM), Costas codes, binary phase codes, and the Frank, P1, P2, P3, and P4 codes. A feature vector based on instantaneous signal properties, second- and higher-order statistics, and time ...

Online Learning-Based Waveform Selection for Improved Vehicle Recognition in Automotive Radar
ICASSP 2023 - 2023 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2023 This paper describes important considerations and challenges associated with online reinforcement-learning based waveform selection for target identification in frequency modulated continuous wave (FMCW) automotive radar systems. We present a novel learning approach based on satisficing Thompson sampling, which quickly identifies a waveform expected to

Radar Waveform Design for Extended Target Recognition under Detection Constraints [PDF]
Mathematical Problems in Engineering, 2012 We address the problem of radar phase‐coded waveform design for extended target recognition in the presence of colored Gaussian disturbance. Phase‐coded waveforms are selected since they can fully exploit the transmit power with sufficient variability.
