The target relative distance and relative speed search method in the radar equipment and the radar equipment

摘要

PROBLEM TO BE SOLVED: To provide a device capable of immediately measuring relative distance and relative velocity of a plurality of targets, by setting limit during combination survey and providing a range for the combination survey. ;SOLUTION: A signal process control part 30 makes the counter (variable) provided to itself K=1, and frequency analyzers 23a and 23b and signal detectors 24a and 24b are operated by the signal process control part 30. Then, a survey range setter part 31 sets a combination survey range in each phase from a present measuring object RK inputted from the signal process control part 30 and a preset measuring velocity range -V_mns-V_pls and outputs to a combination survey part 32. That is, from the present measuring object RK and the preset measuring velocity range -V_mns-V_pls, a, combination survey range is set in each phase. Next, the combination survey part 32 outputs in combination the result in the set range U_mns-U_pls among the output of the signal detector 24a and the output of the signal detector 24b. When a combination is found, the relative velocity R obtained in the survey is outputted to an indicator 15 and the combination Cij(Ui, Dj) is outputted to a velocity measuring part 26.;COPYRIGHT: (C)1999,JPO
