Abstract
A high speed high dynamic range and low power consumption analog correlator for use in a radar sensor. The analog correlator combines various pulse replication schemes with various parallel integrator architectures to improve the detection speed, dynamic range, and power consumption of conventional radar sensors. The analog correlator includes a replica generator, a multiplier, and an integrator module. The replica generator generates a template signal having a plurality of replicated pulse compression radar (PCR) pulses. The multiplier multiplies a received PCR signal with the plurality of replicated PCR pulses. The integrator module is coupled to the multiplier and configured to generate a plurality of analog correlation signals, each of which is based on the multiplying between the received PCR signal and one of the replicated PCR pulses.
