Patent ID: 8576116

Claim:
A radar system comprising: a pulse generator for generating and transmitting a pulse compression radar (PCR) signal having a PCR pulse; a receiver module for receiving a version of the PCR signal reflected by the target; a matched filter for determining a match of a portion of the reflected version of the PCR signal and producing an output signal in response; a controller for determining a time delay based on the output signal of the matched filter; a replica generator for generating a template signal having a plurality of replicated PCR pulses with the time delay determined by the controller; a multiplier coupled to the replica generator for multiplying the received PCR signal with the plurality of replicated PCR pulses of the template signal; an integrator module coupled to the multiplier, and configured to generate a plurality of analog correlation signals, each having a magnitude based on the multiplying between the received PCR signal and one of the plurality of replicated PCR pulses of the template signal; and a target detector configured to detect a position of the target based on the sampled magnitude of each of the plurality of analog correlation signals.
