Facility implementation of adaptive clutter suppression to an existing wind profiler radar: First result

Abstract

Adaptive clutter suppression (ACS) is a technique that mitigates signals from undesired objects by using subarrays. However, because many of existing wind profiler radars (WPRs) have a single-channel receiver, ACS cannot be applied to them. Aiming at implementing ACS capability to existing WPRs, a pilot system composed of auxiliary subarrays, Universal Software Radio Peripheral (USRP), and a workstation, was developed. The use of USRP enabled multi-channel reception and easy development of the software for real-time data processing by using C++. An example, in which ACS was applied to signals collected by the pilot system, is presented. Keywords: radar, clutter, adaptive array, software-defined radio Classification: Sensing References
