Doppler pulse radar with multiple repetition frequencies - transmits blocks of pulses, with pulse repetition frequency being randomly selected

摘要

The Doppler pulse radar with multiple repetition frequencies has blocks of large numbers of pulses. When radar antenna sweeps fixed point target the transmitter emits a sequence of blocks of successive pulses. Each block contains pulses of same width where the pulses in each block are transmitted at different repetition frequencies. Each block contains the same large number of pulses. During a sequence the pulse repetition frequencies for the blocks are randomly selected.
