3) 0.5s after the seeker loses the target, it will return to the preset frame command following state until it can track normally again;
4) After the seeker recaptures and tracks the target, the photoelectric information and line of sight angular velocity will return to normal output;
5) If the seeker determines that it has entered the blind spot, the line of sight Angular velocity output is zero;
