摘要
高频地波雷达工作在电磁频谱密集的短波频段,为了提高雷达抗干扰性能,可利用若干个干净频段合成雷达的有效带宽。研究了一种非连续谱线性调频中断雷达波形,提出了针对这种雷达波形的二维信号处理方案。仿真结果表明:该方案能有效地抑制距离旁瓣,提高回波信号检测目标的动态范围。
It is often difficult to find appropriate clear operating channels in the comparatively limited and congested high-frequency band. In order to improve the performance of radar for anti-jamming, the synthesized wide band waveform is used in this paper. The paper analyzes a Frequency Modulated Interrupted Wave （FMICW） radar signal with discontinuous spectra and proposes a velocity-range processing method. Simulation results show that the new method can suppress range sidelobes effectively, and achieve better range resolution ability and detection for weak echoes.
