STUDY ON ROBUST VARIABLE STRUCTURE GUIDANCE LAW

Measurement noise of sensor in guidance system is the main cause of degradation of guidance performance. To reduce its effects, a certain measure must be taken according to the signal to noise ratio in the guidance loop. In this paper, the robust guidance under the measurement noise of relative range rate is studied. A variable structure guidance law is first proposed, then two different cases are considered.The deterministic relationships that the guidance law parameters must meet for robust guidance and successful interception are presented. The results are very helpful to the designs of modern advanced radar guidance systems.
