Abstract:

The problem of how to control the gimbal strap stabilization platform of a phase array seeker is studied. The beam space scanning is available by controlling array transmitting wave front through a phase shifter embedded in the antenna array element. This kind of phase array radar can solve the quick scanning problem and accomplish target tracking. Besides, the disturbing influence to accuracy of target tracking due to missile body attitude movement can be eliminated during target tracking, and the good tracking property to static  or moving targets is guaranteed. In order to decrease the influence of missle motion on the target measuring, a strapdown stabilization platform is used to maintain antenna’s stabitity for a radar seeker. Based on the compensation principle, angle compensation algorithms are deduced and simulated.
