%X A hybrid parallel PN code acquisition scheme is investigated for the burst mode spread spectrum communication with high doppler frequency offset.Based on LEO satellite channel,analyses of post detection integration and detection threshold to average acquisition time are given.Aimed at the minimum acquisition time,an optimal threshold and post detection integration are put forward.
