Design of low sidelobe random radar signal by frequency-domain modulation method.

A novel method for the design of random radar signal with low sidelobe is proposed in this study. Firstly, the authors modulate the amplitude spectrum of the designed radar signal using a Gaussian window and phase spectrum using a random sequence. Then the inverse Fourier transformation is adopted to obtain the time-domain designed random radar signal. The random radar signal possesses low sidelobe thanks to its Gaussian power spectral density and random waveform owing to its random phase spectrum. The performance of the designed random radar signal is examined by both numerical simulation and real data experiment with dual-polarisation radar, where the polarimetric micro-Doppler of a pedestrian is demonstrated.
