Patent ID: 7466261

Claim:
A RADAR system comprising a set of RADAR apparatuses, each apparatus comprising: a processor; a pulse unit in signal communication with the processor, the pulse unit having a first delay stage configured to provide a plurality of first pulses and a second delay stage configured to provide a plurality of second pulses, each first pulse having a variable delay controlled by the processor to allow one of the plurality of second pulses to follow each first pulse; a waveform signal generator in signal communication with the pulse unit, the waveform signal generator for generating a waveform signal in response to each pulse of the first and second plurality of pulses; a set of radar antennas in signal communication with the waveform signal generator, the set of antennas for transmitting a burst of microwave energy in response to each waveform signal generated by the waveform signal generator and to receive a plurality of reflected bursts associated with each said burst of microwave energy transmitted from the set of antennas; an acquisition unit in signal communication with the set of antennas for developing and amplifying a finite window integral of at least one reflected burst; and a pre-processor in signal communication with the acquisition unit and the processor, the pre-processor for digitizing and storing information relating to each finite window integral for subsequent processing.
