  SPiDR Hostile Fire Radar delivers stealthy, speed-of-light detection of incoming fire
line
Syntonics’ Staring Projectile Detection Radar (SPiDR) uses stealthy ultra wideband “noise” radar to detect incoming and near-miss projectiles ranging from slow RPGs to fast rifle bullets. Staring ultra wideband (UWB) noise radar are lightweight, elegantly simple, intrinsically low cost/low power devices that use low probability-of-detection (LPD) spread-spectrum radio frequency signals to detect and range on objects. Using LPD signals at power levels comparable to the environmental RF noise floor means the radar can operate without a detectable electronic signature.

9-Beam Field of ViewWithin approximately 20 milliseconds of hostile fire, SPiDR annunciates the relative bearing to the firing point(s) and provide continuous relative bearings to the incoming projectile(s) using a combination of audio and video displays. SPiDR can:

  • Detect incoming projectiles with velocities ranging from ~350 fps (an RPG), up to ~4400 fps (the fastest rifle bullet). This velocity range is adjustable in software.
  • Electronically trigger countermeasures and/or alarms after a hostile projectile moves only 20 feet towards a SPiDR unit.
  • Ignore outgoing projectiles (i.e., return fire), noise, sunshine, bright lights, all sonic effects, and airborne objects such as other aircraft, rocks and dust.
  • Operate stealthily due to the use of spread spectrum technology.
sensorSPiDR’s detection and ranging technique is intrinsically immune to platform vibration and maneuvering. Its radar modules are small and can be mechanically integrated in a variety of ways including as conformal patches on the platform alongside existing threat sensors, or as a single multi-sided squat pyramid. SPiDR’s user interface can be integrated with the AN/AVR-2B Laser Warning System or Advanced Aircraft Survivability Equipment (AASE).
