Staggered Modulation in Beam Riding Guidance

ABSTRACT

In beam riding missile, many techniques are used to obtain the misalignment of the missile position from the tracker scan axis. The misalignment information is required in two dimensions and two electrical parameters are necessary to provide this information. Signal received at the missile are amplitude modulated and depth of modulation provides one parameter. The other parameter can be obtained by sending a refe nce signal to the missile using some modulation in the transmitted pulses other than amplitude modulation. In this paper, a staggered modulation technique has been described which gives this information.
