Outline
By constructing an angle tracking loop model and performing simulations in the phased array TT&C (Telemetry, Tracking and Command) system, it is used to assist in designing the parameters for the α-β filtering estimation algorithm in the angle tracking loop and the closed-loop period and delay time of the entire loop. Firstly, the equipment composition of the phased array antenna angle tracking system is introduced, and a simulation model of the angle tracking loop is constructed. Then, when the parameters of the filtering estimation algorithm and the closed-loop period and delay time of the angle tracking loop change, the step signal is used to test the dynamic response performance of the angle tracking loop, and based on this, the design parameters of each link in the loop are determined. Subsequently, constant-velocity signals and sinusoidal signals are used to simulate the maneuvering characteristics of the flight target, and the lag error of the angle tracking loop is simulated to verify whether the design parameters meet the usage requirements of the system. Finally, the sinusoidal signal is used to simulate the disturbance characteristics of the antenna carrier platform. The anti-disturbance performance of the angle tracking loop is verified through loop lag error simulation, and by simply improving the filtering estimation algorithm, the anti-disturbance performance of the loop is improved. Experimental results demonstrate that modeling and simulation of the angle tracking loop enable rapid parameter and algorithm design for all components in the loop, significantly reducing trial-and-error costs.
