摘要
A detailed analysis for the performance of TDOA based passive radar localization systems is provided. The system considered in the analyses consists of four sensors and associated receiver blocks, samplers, and signal processors. Arrival time for the radar pulses are obtained by adaptive thrsholding. Cramer-Rao bounds of TOA and TDOA are obtained. The effects of the receiver bandwidth and the sampling rate on estimation accuracy are investigated. A simple interpolation technique that significantly enhances the performance is described. A simple but efficient method to combine the TDOA measurements from the No antenna pairs is proposed. Final v, the accuracy of the resultant location estimation obtained through triangulation is obtained.
