▎EW Mesh
Controlled Reception Pattern Antenna/ CRPA
Adaptive antenna array that nulls jammers by steering its reception pattern.
Definition
A CRPA is a multi-element GNSS or comms antenna that steers nulls toward jamming sources while maintaining gain on legitimate signals. CRPAs are the dominant hardware countermeasure to GPS jamming on aircraft, missiles, and high-value ground platforms, and the principle extends to comms antennas in dense EW environments.
