技術摘要:
一種空對地飛彈雷達偵測方法及系統,係將數個部署在不同位置的感測器所感測到之一標的飛彈的反射波訊號先以一FSK/LFM整合訊號接收單元計算出該標的飛彈之相對距離及相對速度,再將該計算出之標的飛彈之相對距離及相對速度分別經由二階線性卡門濾波器而求得該標的飛彈之相對距離、相對速度、及相對加速度,最後將該各個二階線性卡門濾波器求得之標的飛彈之相對距離、相對速度、及相對加速度以三邊測量方法計算求得該標的飛彈在x、y、z各個方向的位置、速度、加速度之位置資料。
A method and system for predicting a trajectory of an air-to-surface target missile is provided, including detecting a plurality of echo wave signals from the target missile through a plurality of sensors deployed at various locations relative to the target missile, extracting at least one range distance and at least one radial velocity, respectively, from the detected echo wave signals from the sensors by using a hybrid FSK/LFM unit, using a two-stage Kalman filter to filter the computed range distance and radial velocity to obtain a relative distance, a relative velocity and a relative acceleration, respectively, of the target missile, and finally applying trilateration on the relative distance, relative velocity and relative acceleration of the target missile from each two-stage Kalman filter to obtain a location, velocity and acceleration along the x, y, z directions.
