RADAR SYSTEM AND ITS SIGNAL PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To calculate the Doppler velocity of high reliability even at the time, the deviation of velocity distribution is large or folding of the velocity is occurred. SOLUTION: The Doppler velocity calculation process is constituted such that: the velocity spectrum representing the power intensity distribution of the Doppler velocity value of each power intensity is transformed into the power vector of the polar coordinate system (step S3a); the resultant power vector of the polar coordinate is composited then the power resultant vector is obtained (step S3b); the angle of deviation of the above obtained power resultant vector is calculated (step S3c); and the Doppler velocity is calculated based on the deviation angle of the power resultant vector (step S3d).
