I. NLMU3000A 1535nm Low-Altitude Security Telemetry Core

Precision Erbium-Glass Laser Integration for Advanced UAV Detection

Tracking micro-UAVs in complex low-altitude airspace requires specialized optical calibration far beyond standard distance measurement. Engineered exclusively to solve this challenge, the NLMU3000A functions as a dedicated 3km Anti-Drone Laser Sensor. Rather than generalized ranging, this 1535nm DPSS system is fine-tuned to capture exceptionally small radar cross-sections. It successfully locks onto 0.2×0.3m profiles (equivalent to a DJI Phantom 4) at distances of ≥3km, and 0.1×0.2m targets (DJI Mavic 3 Pro) at ≥2km. As the detection scale expands, the module captures human profiles (1.7×0.5m) at ≥5km, vehicular assets at ≥8km, and pushes its absolute limit to 12km for large infrastructure.To guarantee pristine data integrity for electro-optical payloads, this 3km Anti-Drone Laser Sensor leverages distance gating and first/last target logic to actively strip away environmental clutter. Validated under ≤60% relative humidity, it enforces a strict ≤1% False Alarm Rate (FAR) while maintaining a precision deviation of just ≤±1m. Packaged in a ruggedized, IP67-sealed chassis that weighs strictly ≤660g, this Class 1 eye-safe module performs continuous self-diagnostics during operation. Ultimately, this Low-Altitude Security Telemetry Core delivers the high-fidelity spatial data mandatory for automated perimeter defense and rapid-response tracking arrays.
