FUNCTION

A. It has a self-check function;
B. It can be powered on and bind the laser code according to the instructions of the rocket navigation and guidance device;
C. It can preset the frame angle according to the instructions of the rocket navigation and guidance device (before capturing the target, and after entering the memory tracking and memory timeout states);
D. It can automatically capture and track the target;
E. It can recapture and track the target after losing the target, and output the guidance information normally;
F. It can output the guidance information such as the line of sight angular velocity and frame angle signal to the rocket navigation and guidance device;
G. It can safely and reliably provide the shield ejection signal output by the navigation and guidance device to the nose cone assembly;
H. It has the function of a hit-off switch, and provides a dual-path hit off signal to the fuze at the moment the seeker touches the ground. The hit-off switch is required to be safe and reliable;
I. It can send the line of sight angular velocity, frame angle signal, received laser energy intensity, seeker status information, current laser code, seeker gain control status information, software version number, product batch number, manufacturer code and other information to the telemetry device;
J. It should have an anti-collision frame function. k) It is possible to achieve multiple rockets attacking multiple targets simultaneously (targets are illuminated using different codes);
K. Definition of frame angle and line of sight angular velocity polarity
L. Looking back from the seeker (assuming the current frame angle is 0), when the target is on the left side of the seeker center axis, the frame moves, outputs the positive yaw frame angle and yaw line of sight angular velocity; when the target is on the upper side of the seeker center axis, the frame moves, outputs the positive pitch frame angle and pitch line of sight angular velocity;
