The AN/VLQ-1010 PAVE HOPE system was a self-defence system fitted to larger UNSC vehicles to provide long range protection against RADAR threats. The system works by providing active cancellation, matching the frequency of enemy RADAR signals and cancelling them out with matched frequencies, effectively silencing enemy RADARs. While highly effective against most RADARs, including vehicle, air and missile mounted RADARs, it does have trouble engaging AESA styled RADARs, though when backed up by A.I. support, it can be countered.
