In a binary phase-coded pulse compression type pulsed energy system, means for synchronously transmitting two separately binary coded signals, the code for each signal having an autocorrelation function exhibiting a maximum synchronously occurring with that of the other coded signal, the two autocorrelation functions, when combined, being mutually cancelling except at the synchronous occurrence of the maxima of the autocorrelation functions.

In a phase-coded pulse-compression type pulsed energy system, dual code means for reducing the sidelobes of the autocorrelation funcTion and comprising means for synchronously transmitting two phase-coded, pulsed carrier frequencies, the phase code of each frequency being the compliment of the other; receiver-decoder means responsive to said echoes of said two phase-coded frequencies for providing a combined pulse compression output signal.
