Title:
REDUCTION OF TRACING LOOP BAND WIDTH HAVING ADAPTABILITY IN CLUTTER SIGHT
Document Type and Number:
Japanese Patent JPH07177412
Kind Code:
A
Abstract:
PURPOSE: To decrease disturbance from a clutter by processing target position data and an updated tracking loop gain through the tracking loop of position gate closed loop tracking device as a tracking device inside a raster. CONSTITUTION: A predictive algorithm 37 processes the clutter and velocity data and is used for predicting interference between a main target 27 and a clutter target object 28. The output of this predictive algorithm 37 is updated by an update algorithm 39 while using a crossover frequency for determining an opened loop crossover frequency fc (or band width) concerning the interference. The target position data generated by a main target tracking device 11 and the updated tracking loop gain are processed by a tracking loop 13 for generating the velocity instruction of jimbal at the position gate or closed loop tracking device of tracking device in the raster.
