US-based High Point Aerotechnologies showcased its latest-generation Sawtooth counter-unmanned aircraft system (C-UAS) for the first time at Singapore Airshow 2024 held from 20 to 25 February.

Speaking to Janes, the chief revenue officer of High Point, Evan Hunt, said the Sawtooth C-UAS uses layered technologies to adequately detect unmanned aerial vehicles (UAVs).

The system comprises a passive radio frequency (RF) system, radar, electro-optic/infrared (EO/IR) sensor, and jammers.

As a first step of detection, the Sawtooth uses the passive RF system to detect UAS communications in frequencies that are in known libraries. As the second step, in the case where the frequency is not known, the Sawtooth uses its radar.

“Usually, we use passive RF and radar to find the drone and then cue an EO/IR sensor that is looking in the mid-wave and the short wave, so it is day or night operable,” adds Hunt.
