Abstract:

For the parasitic loop problem caused by beam errors of phased array radar seekers, a beam error parasitic loop model is established. The concept of beam error slope is put forward, and thus the corresponding closed-loop transfer function of parasitic loop model is deduced. Through the Routh criterion, the stability domain of a parasitic loop is determined. The performance of the parasitic loop is analyzed from the time domain and frequency domain, and the guidance parameters that influence the stability of parasitic loops are given. It shows that the stability of parasitic loops is influenced by missile flight attitude and guidance time. Additionally, it was found that the influence of dynamic link order in parasitic loop positive feedback is much smaller than that in parasitic loop negative feedback, but it is more sensitive to the amplitude of beam error slope and more easily unstable. This provides a theoretical basis for industrial design in the future and plays an important role in improving the performance of missiles.
