Abstract:

A radar correcting system has features for providing a corrected radar receiver reflection to a Doppler process unit. The corrected receiver pulse accounts for variances in phase, amplitude and frequency of the transmit pulses. The system has a phase detector that detects the phase difference between a stable oscillator and the transmit signal, providing a complex video or real and imaginary outputs. An operator that will normalize the transmit pulse is determined. The operator is applied to the reflections received by the receiver antenna to remove from the reflections any vagaries due to varieties in the transmit pulses. The data proceeding to the processor deals only with the objects causing the radar reflection.
