基于合成孔径阵列的雷达辐射源被动定位技术研究
Passive Radar Source Localization Using Synthetic Aperture Antenna Array
摘要
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 VT-DOAs 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.关键词
