Abstract

This paper studied the influence of beam point error of Phased Array Strap-down seeker (PASS)and the calibration method. The Last End-off Phase Feeding method and the Round-off Phase Feeding method have been illustrated and analyzed to discuss the reason of the bore-sight error (BSE). The calibration error would influence the bore-sight because of oscillation of BSE. With ignoring the system noise, a method which used the digital phase shifter code has been put forward. The study showed that using the digital phase shifter code to calibrate can reduce the bore-sight error which induced by virtual phase shifting technology effectively.
