Abstract

PURPOSE:To improve the simulation of chaff, and to raise a training effect, by eliminating in order the chaff in a chaff area at a prescribed altitude. CONSTITUTION:This system is provided with an auxiliary memory 2 for specifying a chaff area on a main memory 1 and storing an altitude of chaff and an elimination altitude, a deciding circuit 6 for deciding a diffusion processing or an elimination processing from the chaff altitude and the elimination altitude, an address counter 3 for scanning the CA on the memory 1, an adding an substracting circuit 4 for reading the continuous memory bits in prescribed two directions at every address, a circuit 8 for storing a data corresponding to a data of continuous memory bits in the two directions relating to each address in the two directions, and an address one before said address, a circuit 10 for deciding whether said stored data is varied or not, and a circuit 7 for eliminating a chaff bit in the CA when the data is varied. When the chaff altitude has attained to a prescribed elimination altitude, a chaff in the CA is reduced in order from the circumference and is eliminated.
