Distance measuring defuzzification method for pseudo-random code phase modulation continuous-wave radar

The present invention discloses a pseudorandom code phase modulation continuous wave radar ranging defuzzification method, which involves art continuous wave radar as the target distance measurement. It uses a pseudo-random code of mixed carrier phase modulation by alternative press roll method, performed using the distance range ambiguity resolver remainder of the target in two adjacent turns measured, so that the true distance to the target can be determined. The method can replace the traditional real-time alternate pseudorandom code measurement method, and can enhance the radar detection and handling properties.
