Abstract : A Doppler tolerant binary phase coded pulse compression system. An input pulse is converted to a binary coded sequence of pulses according to a phase code. The sequence pulses is used to frequency code a transmitted carrier. Echo returns are demodulated and supplied to a matched filter for comparison to the binary phase code to detect targets in the echo returns. The detection of targets is independent of target speed. In an alternative embodiment, the binary coded sequence of pulses is used to amplitude code a transmitted carrier. Echo returns are then demodulated and processed in the matched filter to detect targets independence of target speed. (Patents)
