摘要
Abstract
A method for aerial target detection based on GPS reflected signal processing is introduced to accommodate the bad war envi ronment of present Radar. An algorithm for Doppler compensation is presented based on FFT processing with divided GPS reflected signal, which prohibits the destruction to GPS autocorrelation performance caused by Doppler of target. The Doppler ambiguity is corrected and the target speed is measured precisely by choosing the max value of the compressed signal. The simulation results show that the method extends the measurement range and precision with 40Hz Doppler resolution and perfect processing gain, which can realize the aerial target detection.关键词
