INCREASING THE ACCURACY AND RELIABILITY OF NON - CONTACT FUSES WHEN USING ULTRA - WIDEBAND SIGNALS
Ultra - wideband radio signals of the decimeter and centimeter ranges are increasingly being used in a number of areas, including in electronic systems of non - contact fuses. The use of ultrawideband signals can significantly improve the characteristics of the radar system, such as range resolution, noise immunity, and the ability to recognize observed objects. The transition to ultrawideband radar allows consider the use of signals in the form of a short unmodulated pulse. The correlation function of such a signal does not have side lobes, which allows us to expect a better signal - to - noise ratio when using them. It is necessary to assess how significant the gain will be, since the use of signals in the form of a short pulse can be technically difficult. The qualitative characteristics of the systems and the prospects for their use are presented.
