Clutter introduced by wind turbines has a huge influence on the performance of PSR (primary surveillance radars) systems. The ever-increasing amount of wind turbines, calls for a mitigation technique which minimizes the performance degradation of the system in these high clutter areas. Due to the complexity of the concept, and the large number of variables, there is no single solution which will solve the clutter problem in all cases. lntersoft-Electronics offers a range of mitigation techniques to cover all situations. Starting from gap fillers until new or upgraded windfarm 'resistant' sensors The lntersoft-Electronics windfarm resistant sensors are based on the NGSP (Next Generation Signal Processor). The lntersoft Vertical Clutter Cancellation (VCC) technique enables the detection of aircrafts flying directly above turbines. Additionally, the combination of VCC, Range Azimuth Gating (RAG) and high resolution MTD (Moving Target Detector) processing is capable of minimizing the turbine induced clutter up to 40 dB. lncreasing the detection probability in large windfarms and high clutter areas.
