The study of low temperature plasma jet for simulating engine exhaust plume

The engine of an air target could produces a powerful jet plume echo (exhaust plume), if the exhaust plume is exposed to the high frequency waves, which will produces a larger radar cross-section. The low temperature plasma jet, which is stimulated by low power microwave, has characteristics of high electron temperature and low flow temperature, so that it can be experimented in a microwave anechoic chamber. Therefore, this thesis proposes a low - temperature plasma jet for simulating the engine plasma exhaust plume, that makes it possible to analyze the RCS of plasma exhaust plume experimentally.
