CRPA for Anti-jamming Capability
Rajpal Singh, Prof Rajesh Bodade · ASIAN JOURNAL OF CONVERGENCE IN TECHNOLOGY · 2024
Controlled Reception Pattern Antennas (CRPAs) are designed to optimize the reception and processing of GPS/GNSS signals, minimizing interference while maximizing accuracy. By leveraging multiple antenna elements and advanced signal processing techniques, CRPAs achieve these objectives effectively. These systems are increasingly being adopted, particularly in the Defense sector. CRPAs are highly efficient in countering jamming and spoofing, as they dynamically adjust to mitigate such disruptive signals. To implement null-steering and beamforming techniques, it is essential to determine the direction of the interference or jammer. With the widespread use of GPS in defense equipment, ensuring reliable GPS performance in mission-critical operations, especially in jamming environments, is vital. As such, studying this technology within systems that can provide anti-jamming capabilities for GPS-enabled devices—such as drones, GPS receivers, target acquisition systems in firearms, tanks, and helicopters—is crucial.
