摘要/Abstract

摘要： 本文引入被动合成孔径天线阵列新概念，将不同时间位于不同飞行位置的同一接收机视为合成孔径天线阵元，充分利用小型飞行器的空间运动特性及雷达脉冲信号的周期旋转特性，给出雷达辐射源信号虚拟到达时间差精确估计方法，并给出基于虚拟到达时间差的雷达辐射源被动定位方程构建方法及闭式求解算法，以实现雷达辐射源的快速可靠定位.计算机仿真验证了所提算法性能，并证明本文算法针对搜索警戒雷达等脉冲规律稳定的雷达辐射源具有较高的定位实用价值.

Abstract: The new concept of Passive Synthetic Aperture Antenna Array (PSAAA) is introduced into this paper.The same receiver carried by small aircraft is virtually taken as PSAAA element at different flight track position at multiple different moments.Using the characteristics of aircraft space movement and radar antenna circular rotation,an effective method to estimate the passive localization information Virtual Time Differences of Arrival (VTDOAs) is proposed.Based on VTDOAs estimation,they are proposed that the construction method for a binary quadratic localization equation group and a closed-form solution algorithm for radar position estimation.Simulations corroborate the performance of the proposed methods and it's proved that the proposed passive radar source localization method based on PSAAA is applicable for search alert radars in practical applications.

Key words: passive localization, synthetic aperture antenna array, radar source, virtual time differences of arrival
