Abstract

Aiming at the low estimation accuracy of the arrival time of intra pulse modulation radar signal in low SNR environment, an estimation algorithm of radar signal arrival time based on correlated accumulation was proposed. The first order autocorrelation operation of the signal was carried out by using this algorithm, then the arrival time of the signal and the rough estimation of pulse width were obtained by carrying out the moving average, and then the reverse accumulation was carried out and the detection function was built. Subsequently the precise estimation of the arrival time was obtained by searching the location of the maximum value of search function. The Monte Carlo simulation experiments show that the proposed algorithm has strong robustness to the intra pulse modulation of signal, and has high estimation accuracy and low computation volume, which is convenient for real-time processing.

Key words： time-of-arrival estimation; correlation; intra pulse modulation; Monte Carlo simulation
