摘要
Dynamic spectrum allocation requires realtime adjustment of operating frequency and bandwidth in future cognitive radar transmitters. We demonstrate the hastening of a previous frequency-agile reconfiguration algorithm by using prior search endpoints to intelligently inform the starting location of the next search at a previously visited frequency. Measurement results are shown for successive reconfiguration between 10 operating frequencies within the S-band radar allocation. Experimental results demonstrate improved power-added efficiency and speed from the initial information, improving the algorithm's usefulness in real-time reconfigurable transmitters.
