摘要
针对线性调频中断连续波(FMICW)波形体制,研究了分布式多频FMICW波形参数的设计方法。给出了克服多频多普勒频率混叠和距离混叠的设计原则,以适应多站海洋回波混叠、组合频率干扰和电离层干扰的要求。通过分布式高频地波雷达海洋探测试验,验证了波形参数设计的有效性。
For linear frequency modulated interrupted continuous wave（FMICW）form system,the design method for waveform parameter of distributed multi-frequency FMICW is studied.The design principles for avoiding Doppler frequency aliasing and distance aliasing are given,in order to meet the requirements of multi-sites sea echo aliasing,combination frequency interference and ionospheric interference.Through sea detection test of distributed HFSWR,demonstrates the effectiveness of design method for waveform parameter.
