The overall aim of the proposed PhD is to improve the simulation techniques available for the design of radio-frequency (RF) systems; in particular the radar receiver, a system which must be able to detect weak electromagnetic (EM) radiation and yet be protected from potential damage by a large incoming signal. In order to meet these contradictory requirements, devices known as receiver protectors are installed in front of the receiver and allow small signals through, but reflect large signals. These devices need to be modelled accurately during the design process to ensure that they will exhibit the required RF performance. The project will focus upon accurately modelling these devices using a number of novel computational techniques currently under development at the Univsersity of Nottingham (namely the Transmission Line Modelling method and Boundary Element Method) and progessively improving the techniques to ensure they yield more accurate models.

拟议的博士学位的总体目标是改善可用于射频（RF）系统设计的仿真技术;特别是雷达接收器，该系统必须能够检测到微弱的电磁（EM）辐射，但应保护其免受大输入信号的潜在损害。为了满足这些相互矛盾的要求，在接收器前面安装了称为接收器保护器的装置，允许小信号通过，但反射大信号。这些器件需要在设计过程中准确建模，以确保它们能够表现出所需的RF性能。该项目的重点是使用诺丁汉大学目前正在开发的一些新的计算技术（即传输线建模方法和边界元方法）对这些设备进行准确建模，并不断改进这些技术，以确保它们产生更准确的模型。
