Research on Total Error of Anti-Radiation Missile against Target Radiation Source Shutdown

摘要

This paper established the total error model of Anti-Radiation Missile under condition of target radiation source shutdown, which includes three dimensional passive location error model using information of azimuth and elevation angle as well as their changing rates, and gyroscope drift error model of Strap-down Inertial Navigation System. By analyzing the three dimensional passive location method to moving emitter using single stationary observer, the paper had a research to the hit probability of Anti-Radiation Missile under various flying conditions. If higher hit probability is required, the missile should increase its azimuth and elevation angle as much as possible while not to overstep its attack angle. Simulation result showed that the shutdown occasion of radiation source did much influence to the hit probability of Anti-Radiation Missile, which has great meaning to improve he bat efficiency of Anti-Radiation Missile.
