Accurate and efficient analysis of the EM environment due to naval radars

The application of computational Electromagnetic (EM) tools to analyse the effects of radar systems on large, complex platforms are presented in this paper. In particular, significant cost and time savings are achieved early in the design process with the accurate modelling of applications such as RF hazards and the siting/installed performance of radars. The effectiveness of computational analysis is dependent upon on both the sophistication of the EM software and the quality of the CAD in containing perhaps physically small but electromagnetically significant detail. An example is given of the effect of a surveillance radar onboard the UK Aircraft Carrier (CVF).
