Abstract: A programmable digital device designed to perform a matched filtering opeion on arbitrary binary phase-coded signals. The technique is used in secure communication systems and for various radar and missile fuzing operations. The essential features minimize the component by the specific networks for the summing units containing unique combinations of digital components. The output is converted to sign-magnitude format.

Abstract: A double sideband linear frequency modulation technique for radar applications is disclosed for obtaining simultaneous range and doppler measurements. The method of obtaining measurements is useful in a variety of radar applications; however, the most promising area is in continuous wave radar systems. Linear Frequency Modulated (LFM) waveforms of both increasing and decreasing frequency are simultaneously transmitted. Upon reception, these sideband signals are combined coherently to give an output that is a function of the target's radial velocity. The received signals are also processed separately to obtain target ranging information.
