Abstract Based on Linear Frequency Modulated (LFM) pulse compression signal, a system which has two resolution with 1200MHz carrier and 200MHz and 66.7MHz bandwidth, is designed and implemented. According to the measurement results, the spurious signals involved in the system output as well as the harmonic signals are lower than - 55dB, the ripple in the band is below 2dB, and pulse compression Ratio of Mainlobe to Sidelobe (RMS) reaches 30dB. The system is quite stable and its performance meets the requirement of actual application.
