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