| 分析了二次雷达系统中采用的询问旁瓣抑制（ISLS）技术，针对其不能完全消除询问旁瓣干
扰、无法调节询问方位覆盖范围的不足，提出了一种新的设计方案，采用和（Σ）、差（Δ
）、全向（Ω）三通道发射询问信号的方法来消除旁瓣干扰，并通过采用询问信号传递波束
调节因子的方法实现系统询问有效方位波束宽度的自动调节。该方案提高了系统的询问旁瓣
抑制能力、抗干扰能力和平台适应性，已成功应用于某工程。 |

| Abstract: |
| The Interrogation Side Lobe Suppression(ISLS) technique applied in Se
condary Surveillance Radar(SSR) system is analyzed. Generally, even if IS
LS technique is adopted, however, transponder replies can not be prevented compl
etely and the coverage of interrogation in azimuth can not be adjusted automatic
ally. In view of these shortcomings, a new design is proposed. In the design, in
terrogation signal is radiated from sum(Σ), difference(Δ), omni-directional(
Ω) channels to eliminate the interference of side lobe. Beam control factor is
carried in interrogation signal to realize automatic control of efficient beam w
idth in azimuth of interrogator antenna. The design improves the abilities of si
de lobe suppression, anti-jamming, and platform applicability of SSR system. Th
e design has been successfully applied in a project. |
| Key words: secondary surveillance radar(SSR) interrogation side lobe suppression(ISLS) omni-directional channel beam control factor |
