The SJ-2-80 Platform Laser Seeker rapidly identifies and captures laser-designated targets during terminal guidance, calculates the deviation angle between target and optical axis, and guides the vehicle precisely onto the target. A four-quadrant laser detector working at the 1.064 µm designation wavelength provides a ±15° field of view with a ±10° linear zone, detecting coded laser energy beyond 3000 m with a blind zone of 50 m or less; both precise frequency code and pseudo-random code encoding are supported. Unlike the strapdown SJ-1-70, the SJ-2-80 integrates a two-axis stabilization platform (pitch −25° to +25°, yaw −25° to +25°) with 2% isolation and 0.2° frame angle accuracy, widening the effective capture envelope during maneuvering flight. Detection accuracy is 0.3° or better with ≤5 ms dynamic output delay and 1 s target reacquisition after signal loss. The Φ90 × 100 mm customizable housing weighs ≤900 g with 300 g overload tolerance, draws ≤15 W from an 18–32 V supply, and operates from −40 °C to +60 °C — widely applicable to various smart munitions.
