Abstract:
1. A target detection device, comprising: a transmitting unit, which transmits a detecting pulse for detecting 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 generate measured values of distance and measured values of velocity according to the reflected pulses 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 said measured value of distance and said measured value of velocity produced by corresponding measuring unit so as to generate respectively an estimation value of distance, an estimation value of velocity and an estimation value of acceleration; and an arithmetic unit connecting to said plural two-stage linear Kalman filters, which proceeds a triangulation operation according to said estimation values of distance, said estimation values of velocity and said estimation values of acceleration so as to generate component values of distance, component values of velocity and component values of acceleration with respect to the target.
