Pulse compression Eclipsing-Repair

For radars operating with medium to high pulse repetition frequency (PRF), a loss in detection performance can result when the arrival of return echoes coincides with the transmission of a pulse, during which time the receiver is turned off. This so-called ldquoeclipsing lossrdquo is due to the partial reception of the reflected waveform corresponding to a given range cell. In this paper, the MMSE-based adaptive pulse compression (APC) algorithm is modified to account for pulse eclipsing effects in order to improve the resolution accuracy of the eclipsed regions. Simulation results for the subsequent eclipsing-repair APC (APC-ER) are compared to results obtained from matched filtering and mismatched filtering, both of which are known to degrade in the presence of eclipsing, where it is found that APC-ER significantly improves the estimation of the eclipsed region.
