The compact STA-LRW1000X laser rangefinding module is specifically designed for deep integration into army and navy air defense systems. It adopts advanced diode‑pumped erbium-glass laser technology, offering high reliability and low maintenance costs. With a beam divergence of 2 mrad, it can accurately measure distances up to 1000 meters against UAV targets with a cross-ectional area of 0.1 m², making it a core key component of counter-UAV systems.
Main Functions:
1)Single ranging and continuous ranging;
2) Responding to laser ranging commands and stopping ranging at any time according to the stop command;
3) Outputs distance data and status information once per pulse during ranging;
4) It can report the cumulative number of transmitted laser pulses (no loss of power down);
5) Distance selection, before and after target indication;
6) Self-test function.
