Patent ID: 8305256

Claim:
A method for radar determination of target range and velocity, said method comprising the steps of: transmitting a plurality of continuous-wave linearly-frequency-modulated signals toward a target, to generate return signals; receiving return signals including contiguous continuous-wave linearly-frequency-modulated signals with superposed amplitude-range and frequency components associated with the target; separating said return signals into predetermined different frequency bands, to generate, within each of said frequency bands, band-limited return signal subpulses; frequency-modulating each of said band-limited return signal subpulses to a common baseband frequency to therby generate a plurality of baseband return signal subpulses; match-filtering each of said baseband return signal subpulses with a linear-frequency-modulated matched filter at said common baseband frequency, to generate matched-filtered return signal subpulses; aligning said matched-filtered return signal subpulses in time, to generate time-aligned matched-filtered return signal subpulses; and Doppler-filtering said time-aligned matched-filtered return signal subpulses, to generate Doppler signals representing the range and velocity of said target.
