摘要
针对二次雷达中询问旁瓣干扰现象,分析了询问旁瓣抑制技术的抗干扰原理和实现方式,以及其在多询问机工作环境中对识别概率的影响,在实际工程应用中,可通过和、差、全向三通道发射询问信号实现旁瓣覆盖率100%。
This paper analyzes the Technology of Interrogation Side-lobe Suppression(ISLS) in SSR system,and its effect on the probability of identification in multi-interrogators situation is also studied.In actual project application,interrogation signal is radiated from sum(Σ),difference(Δ),omni directional(Ω) channels to cover the whole side-lobe beams.
