Abstract

Abstract:

The phased array radar seeker is at present the top choice in the new generation air to air missiles guidance system, and beam stabilization is the first problem to be solved in this application. This paper proposes a beam stabilization algorithm for phased array radar seeker based on the theory of the invariability of beam orientation in inertial space. It simulates and analyzes the main factors that affect the isolation performance of a phased array radar seeker. The simulation results indicate that this algorithm possesses good performance and high engineering feasibilty. They also demonstrate that decreasing the cycle of the rate gyroscope’s data and the beam control period as well as introducing a transmission delay compensation algorithm of the gyroscope will significantly improve the isolation performance of the seeker.

Key words: phased array radar seeker, beam, stabilization, air to air missile, strapdown seeker, mathematical stabilization platform
