Low-Sidelobe Design of Monopulse Difference Beam Based on Convex Optimization

摘要:

针对弹载单脉冲雷达在杂波背景下由于差路信号信杂比降低导致测角精度降低的问题，提出了一种基于凸优化的低副瓣差波束方向图优化设计方法。通过低副瓣及副瓣零陷方向图优化仿真实例，验证了所提方法的可行性。该方法可以用于弹载单脉冲雷达抗地海杂波干扰，能够提升其测角性能。

Abstract:

To address the issue of degraded angle measurement accuracy in missile-borne monopulse radar due to reduced signal-to-clutter ratio in the difference channel under cluttered environments, a convex optimization-based design method for low-sidelobe difference beam pattern synthesis was proposed. Simulation examples of optimized low-sidelobe and sidelobe nulling patterns validate the feasibility of the proposed method. This method is applicable to missile-borne monopulse radar systems to mitigate ground/sea clutter interference and enhance angle measurement performance.
