A multifunctional, modular, and scalable digital radar electromagnetic environment simulation application system based on a local area network is designed and proposed to address the issues of high cost, long term, and difficulty in constructing a real radar electromagnetic environment. It can realistically simulate the electromagnetic environment faced by radar, reduce evaluation and verification costs, improve efficiency, and also have high security. By leveraging the VC development platform and adopting a client/server architecture pattern, distributed application processing of client program requests is achieved. Based on this system structure, computer processing power can be fully utilized, with fast response speed and low network communication volume, ensuring system flexibility while also reducing the demand for hardware resources.

Analysis of radars systems requires representing the radar operation and performance in the context of the overall system and the external environment. The radar performance must be evaluated, and the impact of radar operation on system performance must be quantified. In this paper, we simulate radar system by using the Radar Designer app in MATLAB, analysis the system to decide whether a set of performance requirements, such as pd and SNR, have been satisfied according to the specifications. This paper also discusses the loss of radar system in rain, and the performance of radar system when detecting Small UAS.
