Abstract
A method to improve a system's signal performance may comprise: generating a first signal, transmitting the first signal, receiving the first signal, and generating a second signal. The method may further comprise: identifying signal distortions generated by at least one of, a transmitter hardware that transmits the first signal and a receiver hardware that receives the first signal, modifying the second signal based upon the identified signal distortions, correlating the first signal and the second signal by a correlator to generate a correlated signal, and outputting the correlated signal.

A method to improve a system's signal performance comprises:
- generating a first signal;
- transmitting the first signal;
- receiving the first signal;
- generating a second signal;
- identifying signal distortions generated by at least one of, a transmitter hardware that transmits the first signal and a receiver hardware that receives the first signal;
- modifying the second signal based upon the identified signal distortions;
- correlating the first signal and the second signal by a correlator to generate a correlated signal;
- and
- outputting the correlated signal.
A system to improve signal performance comprising:
- a first signal generator to generate a first signal;
- a transmitter to transmit the first signal;
- a receiver to receive the first signal;
- a second signal generator to generate a second signal;
- a signal modifier to modify the second signal based upon identifiable hardware errors from at least one of:
- a transmitter hardware that transmits the first signal and a receiver hardware that receives the first signal;
- and
- a correlator to correlate the first signal and the second signal to generate a correlated signal.
A pulsed Doppler radar system comprising improved signal performance comprising:
- a first signal generator to generate a first signal;
- a transmitter to transmit the first signal;
- an antenna to receive the first signal;
- a reference signal generator to generate a reference signal;
- and
- a pulse compression filter, wherein the pulse compression filter:
- modifies the reference signal based upon identifiable hardware errors from at least one of a hardware from the first signal generator and a hardware from the antenna;
- and
- correlates the modified reference signal and the received first signal to generate a correlated signal.
