摘要：

Higher-order statistics are proposed to compute and analyze micro-Doppler signatures of radar backscattering related to ground moving targets. The presence of frequency and phase coupling in non-stationary and multi-frequency backscattered radar signals is defined and studied. Method aimed for extraction of frequency and phase coupling by using bicoherence estimation is suggested. Bicoherence-based information features extracted both from computer modeled micro-Doppler radar signatures of walking human and real backscattering radar data are represented, studied and compared. Good correspondence between bicoherence-based radar signatures computed by using modeled and real-life radar returns is demonstrated.
