摘要

本文介绍了一种合成孔径雷达（Synthetic Aperture Radar， SAR）目标特征的操控方法，采用非周期相位调制表面（Phase-Switched Screen， PSS）实现对重要目标图像特性的有效压制. 依靠PSS反射式防护手段，对雷达回波信号进行快-慢时间域的二维联合非周期相位调制，在SAR接收处理后可形成矩形块状压制区域. 通过调控快时间与慢时间码元宽度，可以实现生成矩形区域的面积控制. 该方法本质是一种无源防护方法，兼具响应时间快、不易暴露、设备简单等优势. 在此基础上，本文提出了压制区域面积、压制区域干信比对特征操控效果进行表征，分析了PSS调制参数对操控效果的影响. 最后，SAR实测数据仿真验证了所提方法的有效性.

Abstract

This paper proposes a method for manipulating synthetic aperture radar (SAR) target features based on a phase-switched screen (PSS). The proposed method relies on the PSS reflective protection method to perform fast and slow time two-dimensional joint nonperiodic phase modulation on the radar echo signal. As a result

it can form a controllable rectangular block area after SAR receiving and processing. The proposed method is essentially a passive protection method with the advantages of fast response time

low exposure

and simple equipment. On this basis

this paper uses the barrage area and the jamming signal ratio to characterize the characteristic manipulation effect. It analyzes the influence of PSS modulation parameters on the manipulation effect. Finally

the simulation of the SAR measured data verifies the effectiveness of the proposed method.
