Potential applications for low-Tera-Hertz radar

The paper discusses the applications for which operation at terahertz frequencies can give significant advantages over operation at other wavebands. The review of potential applications must take account of the radar sensitivities which are practical at these wavelengths, including the atmospheric propagation characteristics. The most significant applications would appear to be more compact versions of some which applications for which millimetric radar has been looked at in recent years: automotive sensors, helicopter obstacle warning and missile fusing, although the different target and clutter characteristics at these frequencies are likely to lead to significant differences in the performance of the systems and to novel applications as the phenomenology becomes better characterised.
