Abstract	Range estimation is an important issue of radar system, and its performance is mainly limited by the transmitting bandwidth. To improve the range resolution, the existing approaches often either occupied wider bandwidth or employed some non-linear techniques which cause high complexity. The wider the transmitting bandwidth has not only the more the network resource takes but also the easier the radio frequency interference (RFI) is introduced. The authors propose a new radar system by utilising jointly the compressive sensing (CS) and the proposed virtual expanding technique, referred to as the compressing sensing and virtual expanding (CSVE) radar system. The proposed CSVE radar system not only provides high-range resolution with low cost by saving transmitting bandwidth but also is robust to the bad effect of the RFI by utilising a pre-detection phase at the transmitter and a detection phase at the receiver. Simulation results validate the superiority of the proposed CSVE radar system over both the high-resolution techniques such as Capon, multiple signal classification and matched filter, and the CS step-frequency radar system.
