It is difficult to realize the effective detection and tracking of high speed small target with single pulse working system, which is still used in a certain type of fire control radar. Based on coherent accumulation detection theory, the pulse accumulation detection technology is proposed to improve the target detection performance of fire control radar in this paper. According to the radar equation, the performance improvement is analyzed and calculated. The results show that the proposed method can effectively improve the detection distance and alarm time of the high speed small target.
To improve the tracking accuracy of maneuvering target, a tracking algorithm based on parameter adaptive current statistical (CS) model is proposed. According to the relationship between the acceleration increment and displacement, the acceleration variance is adjusted adaptively. According to the statistical distance of the measurement residuals, the target maneuver characteristics are determined, and then the maneuvering frequency and the filter gain coefficient of the model are adjusted to improve the matching degree between the algorithm model and the target maneuver model. The simulation results show that the tracking algorithm based on the parameter adaptive CS model can improve the tracking performance of the strong maneuvering target.
