H-KM, M-SS, IS, and J-HL proposed a novel weather radar network system (WRNS) in which multi-site weather radars operate in the same frequency band. The proposed system suppresses the inter-site interference by adopting pulse compression with nearly orthogonal codes, and, at the same time, removes the intra-site interference based on a sidelobe suppression technique. H-KM, M-SS, IS, and J-HL showed the feasibility of the proposed frequency-sharing WRNS through computer simulations, taking the performance requirement of a typical single weather radar, WSR-88D, into account. All authors read and approved the final manuscript.
To mitigate damages due to natural disasters and abruptly changing weather, the importance of a weather radar network system (WRNS) is growing. Because radars in the current form of a WRNS operate in distinct frequency bands, operating a WRNS consisting of a large number of radars is very costly in terms of frequency resource. In this paper, we propose 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 computer simulations, we show the feasibility of the proposed system taking the performance requirement of a typical single weather radar into account.
