Research on arrangement method of motorized chaff screen based on cuckoo bird search algorithm
The radar seeker adopts anti-interference technologies such as moving target display and tracking while searching,which leads to a decrease in the interference efficiency of traditional centroid,dilution,and curtain wall style chaff interference methods.A motorizedchaff screen deployment method is proposed to ensure that the energy center of the curtain wall moves continuously over time by coordinating the deployment of chaff bullets by drones and ships,ensuring that the ship successfully escapes the radar beam within an effective time.Firstly,based on the mechanism of motorized chaff screen interference,a chaff screen deployment model is constructed,which includes a radar seeker motion model,a ship motion model,a chaff screen shape model,and a chaff screen motion model.Subsequently,based on the characteristics of the motorized foil curtain model,it is determined to use the cuckoo search algorithm to obtain the deployment plan.Based on this,propose an overall solution approach and construct deployment efficiency conditions(objective function and constraint conditions).Using logistic chaos mechanism to improve the cuckoo search algorithm and establish a replenishment strategy.Finally,the effectiveness of the motorized chaff screen deployment model is analyzed and verified through simulation cases.The results show that compared with conventional chaff screen placement methods,motorized foil screen placement methods can effectively reduce ship escape time,reduce chaff cartridge consumption,and have strong ability to cope with different wind speeds and directions.
