Abstract: A ranging and detecting system such as radar, sonar or the like is arranged to transmit the signature of a desired target. A cross correlation process takes place as the transmitted wave front sweeps past the possible targets. Back-scattered energy is received by a unit having a single optimum bandwidth and a threshold which detects only the desired target.

Abstract: A digital phase tracker includes a memory for storing a signal locked in phase with an external signal and means for maintaining the signal stored within the memory phase synchronized with the external signal as the phase of the external signal varies. The time relationship between positive excursions of the external signal and positive excursions of the stored signal is timed by high-speed clock pulses with clock pulses being added to or subtracted from the memory signal to maintain phase-lock.
