Characterizing CRPAs and Other Adaptive Antennas
白皮书
Anti-jamming and anti-spoofing capabilities are becoming essential features of mission-critical Global Navigation Satellite Systems (GNSS) receivers and dependent systems.
Threats from signal jamming and spoofing are increasing; both from civilian sources (e.g. illegal personal privacy devices (PPDs) intended to mask a commercial vehicle’s whereabouts) and from the use of radio frequency interference (RFI) as an electronic warfare (EW) method deployed by nation states to disrupt an adversary’s operations.
In the military domain, the need to protect mission-critical PNT systems led to the development of adaptive antennas that can be retrofitted to a wide range of GPS receivers. Now, adaptive antennas are also increasingly used in commercial applications such as surveying, mining, and autonomous vehicles.
Adaptive antenna systems need to be thoroughly tested, particularly if they are to be used in safety and liability-critical contexts. In this paper, we will explore the challenges of reliably testing adaptive antennas and provide guidance on establishing test requirements, selecting test equipment, and conducting a test using a radio frequency constellation simulator.
Finally, we’ll set out how Keysight can help with any aspect of adaptive antenna testing — from providing future-proof simulators and software to designing a zoned chamber solution for over-the-air (OTA) testing.
