ABSTRACT:
The disclosed circuit decouples the aiming of an electronic scanning antenna from the motions of its platform which is assumed to be a moving body. It has two independent tracking channels which determine the direction cosines of the beam along pitch and yaw axes of a referential trihedron that is related to the platform and that has its roll axis colinear with the direction of orientation of the antenna. Each of these channels is decoupled from the motions of the platform by the introduction of a variable that is deduced, by a stabilization circuit, from the gyrometrical measurements of an inertial unit linked to the platform. This device makes it easy for the beam of the antenna to carry out a watch scanning operation or target-tracking operation that is independent of the motions of the platform. Should the electronic scanning antenna form part of a homing unit of the missile, it can easily be complemented by a proportional navigation guidance device.
