Title:
FM-CWレーダのミスペアリング判定及び信号処理方法
Document Type and Number:
Japanese Patent JP3753652
Kind Code:
B2
Abstract:
When a new target is detected, if it is determined that the distance difference between the newly detected target and the previously detected target is within a predetermined range, the difference between the relative velocity of the newly detected target and the relative velocity of the previously detected target is obtained to determine whether the difference is greater than a predetermined value DELTA Va, and when the difference is greater than the predetermined value, it is determined that the new target is a target obtained as a result of mispairing. Further, the difference between a distance derivative of the newly detected target over a prescribe time and the relative velocity of the previously detected target is obtained, and when the difference is greater than a predetermined value DELTA Vb which is smaller than the predetermined value DELTA Va, it is determined that the new target is a target obtained as a result of mispairing.
