【 摘 要 】

References(5)The paper presents the waveform analysis and parameters design involved with range resolution, maximum detect range, transmit interval and receive interval, in phase-code interrupted continuous wave (PCICW) radars. More attention is paid to the effect of transmit/receive gating. Range blinds are avoided by ensuring the pulse travels to and from the maximum detect range before the next pulse is emitted. It is shown that certain complementary sets with column orthogonality are adequate for our applications. Although the echo is partially suppressed by the gate, the compressed output retains zero range sidelobe performance. Simulation demonstrates that P4 codes are insentivity to Doppler effect in PCICW radars so it can simplify the receiver complexity, and the experiment shows that the sidelobes level are -90dB compared to the mainlobe.
