FREQUENCY MODULATION RADER SYSTEM

摘要

PURPOSE:To improve the reliability of peak pair by preventing wrong combination and to obtain accurate relative distance and relative speed of a target object, in a frequency modulation rader system. CONSTITUTION:A first pairing means (M2) combines a power spectrum peak in a frequency increase section and a power spectrum peak in a frequency decrease section in a frequency order. A correlative calculation means (M3) calculates the correlative quantity for respective peak pairs combined by the means 1. A calculation prevention means (M4) prevents calculating of relative distance and relative speed based on a lowerly relative peak pair when any peak pair whose relativity is lower than the specified value exists.
