Abstract

The authors analyse the sequential lobing radar (SLR) resistance against the scan rate modulation (SRM) jamming technique. Unlike previous studies, the authors analyse SLRs with sinc antenna patterns, enabling investigation of the sidelobe region's vulnerability. By incorporating second-order angular tracking loops (SOATLs), the first analysis of break-lock probability for SLRs under SRM jamming is introduced. The analysis reveals the influence of SOATL parameters (damping ratio and natural frequency) on both angular root-mean-square-error at low jamming-to-signal-ratio (JSR) region and break-lock probability at high JSR region. Additionally, the impact of squint angle on SLR resistance to SRM jamming is examined. Furthermore, the optimal duty cycle as a function of JSR, which maximises break-lock probability is presented. Significantly, the theoretical results support the 20 dB JSR requirement for SRM effectiveness, often cited experimentally in literature, and extend the theoretical analysis of the SRM technique carried out for the main lobe region of SLRs. This finding bridges the gap between theoretical analysis and practical observations.

击败角度跟踪：扫描速率调制干扰对序贯雷达的综合分析

分析了序贯分叶雷达（SLR）对扫描速率调制（SRM）干扰技术的抗干扰能力。与以前的研究不同，作者分析单反与正弦天线模式，使调查旁瓣区域的脆弱性。通过引入二阶角跟踪环（SOATLs），首次分析了单反在SRM干扰下的断锁概率。分析揭示了SOATL参数（阻尼比和固有频率）对低干扰信号比（JSR）区域角均方根误差和高干扰信号比区域断锁概率的影响。此外，还研究了斜视角度对单反抗SRM干扰的影响。此外，给出了最优占空比作为JSR的函数，使锁断概率最大化。值得注意的是，理论结果支持SRM有效性的20 dB JSR要求，这在文献中经常被实验引用，并扩展了对slr主瓣区域的SRM技术进行的理论分析。这一发现弥合了理论分析和实际观察之间的差距。
