摘要

本文提出了一种在均匀线性阵列中具有空间延迟线消除器(DLC)和非相干积分器的旁瓣消隐(SLB)系统。在建立了SLB系统中目标功率和噪声功率的方程后,开发了所提出的和传统SLB信道的SLB比率函数。利用这些比值函数,估计了一般可探测目标和低雷达截面积目标的最优SLB阈值。蒙特卡洛仿真验证了SLB阈值的结果,表明所提出的SLB信道在旁瓣区域内提供了可靠的性能,没有错误的SLB判决。使用估计的最优阈值,所提出的SLB信道提供了可靠的性能,特别是对于低RCS目标。相反,传统的SLB信道在旁瓣区域中产生许多错误的SLB判决。所提出的合成是获得可靠SLB比率的一种简单但强大的方法。基于这种方法可以开发出各种阵列天线系统中的SLB信道。

Spatial Delay Line Canceler-Based Sidelobe Blanking for Low Radar-Cross-Section Target
This study proposes a sidelobe blanking (SLB) system with a spatial delay line canceler (DLC) and non-coherent integrator in a uniform linear array. After the equations for the target and noise power in the SLB system were established, SLB-ratio functions for the proposed and conventional SLB channels were developed. Using these ratio functions, the optimal SLB thresholds for the general detectable target and low radar-cross-section (RCS) target were estimated. The results of the SLB thresholds were confirmed by the Monte Carlo simulation, which indicated that the proposed SLB channel provides reliable performance without false SLB decisions in the sidelobe region. Using the estimated optimal threshold, the proposed SLB channel provides reliable performance, particularly for low-RCS targets. In contrast, the conventional SLB channel produces numerous false SLB decisions in the sidelobe region. The proposed synthesis is a simple but powerful method for obtaining the reliable SLB ratio. The SLB channel in various array antenna systems can be developed based on this method.
