Abstract

A Frequency Divided Multiple Input Multiple Output (FD-MIMO) radar is proposed, which can synthesize the High Range Resolution Profile (HRRP) by transmitting and receiving narrowband waveforms in different frequency bands without over-demanding system bandwidth. And thanks to short pulse duration, the HRRP of FD-MIMO radar has good Doppler tolerance. But the synthesized HRRP suffers from high-level sidelobes near and far from the mainlobe caused by the discontinuity of the synthesized spectrum and the interferences between the subband waveforms respectively. To suppress them, the reciprocal spectrum filter is applied and the out-of-band attenuation of each subband waveform is utilized. Finally, numerical experiments show the effectiveness of the presented methods.
