WRNS simulator

frequency-sharing weather radar network system (WRNS) simulator

To mitigate damages due to natural disasters and abnormally changing weather, the importance of a weather radar network system (WRNS) is growing. Because radars in the current form of aWRNS operate in distinct frequency ands, operating aWRNS consisting of a large number of radars is very costly in terms of frequency resource. In this simulator, we design a novel WRNS in which multi-site weather radars share the same frequency band. By employing pulse compression with nearly orthogonal polyphase codes and sidelobe removal processing, a weather radar of the proposed frequency-sharing WRNS addresses inter-site and intra-site interferences simultaneously. Through these simulation programs, one can check the feasibility of the proposed system (taking the performance requirement of a typical single weather radar, WSR-88D, into account).
