技術摘要 / Our Technology: |
本發明為一種目標偵測裝置及其方法,其利用一發射單元發射偵測脈波,以偵測目標物,該目標物反射該偵測脈波而產生反射脈波;複數量測單元分別於不同位置接收對應於目標物之反射脈波,且分別依據所接收之反射脈波,各產生距離與速度之量測值;複數二階卡爾曼濾波器分別依據所對應之該量測單元所產生之量測值進行運算,各產生距離、速度與加速度之估算值;一運算單元連接該些二階卡爾曼濾波器,依據該些估算值進行三角定位運算,而產生對應於該目標物之距離分量值、速度分量值與加速度分量值。
This invention relates to a target detection device and its detection method, comprising: a transmitting unit for transmitting a detecting pulse to detect target which then reflects the detecting pulse to generate a reflected pulse; a plurality of measuring units, located at different positions respectively which receive said reflected pulse and generates measured values of distance and measured values of velocity according to the reflected pulse received; a plurality of two-stage linear Kalman filters, corresponding to said plural measuring units respectively, each of said plural two-stage linear Kalman filters proceeds an operation according to the measured values produced by corresponding measuring unit so as to generate respectively the estimation values of distance, velocity and acceleration; an arithmetic unit connecting to said plural two-stage linear Kalman filters, which proceeds a triangulation operation according to said estimation values so as to generate distance component values, velocity component values and acceleration component values with respect to the target.
