Experimental Comparison of stepped multiple frequency CPC with Pulse compression

Authors have developed the stepped multiple frequency Complementary Phase Code (CPC) radar system. The unique radar modulation/demodulation method can achieve both a high range resolution and a long-range detection performance with a narrow band receiver compared with the transmission bandwidth. In this paper, the experimental verification to compare the detection range performances between Stepped multiple frequency CPC and Pulse compression was conducted. The experimental results indicated that the proposed modulation was 1.72 times superior to Pulse compression in the detection range performance on the condition where the transmission bandwidth, observation time, peak power, code length (the number of chips of switching codes), and the number of total pulses were set to be the same.
