三频段准连续波雷达信号目标检测性能分析
Radar Signal Processing for Three Frequency Ranges Quasi-continuous Waveform
摘要
Abstract
A low probability of intercept( LPI) radar, quasi-continuous wave radar integrates the advanta-ges of transceiver isolation of pulse radars and low LPI of continuous wave radars, but its detection per-formance largely depends on the signal form. Ordinary coded signal and LFM signal can not satisfy the re-quirement for target detection, so a three frequency ranges signal and the corresponding transceiver system are designed. The system structure and the parameter selection principle of three frequency ranges signal, target detection principle, fuzzy function, close-blind area resistance are analyzed in detail, and the supe-riority of three frequency ranges signal relative to the phase coded signal and time-sharing signal is pointed out. Simulation demonstrates that the performance of target detection is improved and close-blind area is e-liminated, when three frequency ranges signal is applied to the quasi-continuous wave radar system.关键词
