Ⅰ. Product Overview
The LKFS-M130 is a fixed low-altitude airspace security system that integrates passive RF spectrum sensing and digital RF mitigation in a single 23kg enclosure. Its sensing subsystem operates passively across 300MHz to 6000MHz with a maximum real-time scanning bandwidth of 480MHz, providing a 1-4km detection radius and 360° horizontal coverage, with alert response within 2 seconds or less and concurrent tracking of 40 or more targets. It identifies targets by RF spectrum fingerprint and by parsing broadcast protocols including DJI Drone ID, FAA/EU Remote ID (RID) and WiFi links, against a built-in library of 800+ aircraft models that can be expanded on site; in broadcast message parsing mode it plots both the aircraft and the operator position with 5m positioning accuracy.
The second subsystem is an SDR-based, six-channel digital RF mitigation module covering 360MHz-800MHz, 800MHz-1240MHz, 1360MHz-1800MHz, 2310MHz-2750MHz, 5100MHz-5540MHz and 5540MHz-5980MHz, with a mitigation radius of 0-3km in open, unobstructed conditions and a mitigation response of 5 seconds or less. Frequency-Domain Windowing allows each channel to leave a protection window in which no RF energy is emitted, so the customer's own radio and Wi-Fi frequencies continue to operate. The unit runs on AC 220V with total power consumption of 750W or less, is rated IP66 for 7×24 unattended operation, and includes BeiDou (BDS) timing and positioning, a Web-based management platform, multi-node TCP/IP networking and RESTful API / SDK interfaces for integration with existing security management systems.
