Non-atmospheric Window Millimeter Wave Fuze Exploratory Study

This paper is an important part of Native Defense scientific research fund task "non-atmosphere window millimeter wave fuse exploring study". First, this paper discusses the transmitting attenuation property of non-atmosphere window millimeter wave, because of the great atmosphere attenuation in this band. It confirms this task is feasible in the theory. Based on the all attenuation , we can find the short range radar worked in this band is affected by action distance and interfere.After completed theory analysis, next work is the design of actual instrument and theory analysis of working system. This paper mainly analyses dispersion frequency signals' time and frequency property of triangle wave modulation. Real 5mm dispersion frequency signal is collected. The theory data and real data are compared and analyzed. It shows 5mm radar forepart is practicable, it also supplies theory base to design back signal processing circuit.At last , the paper discusses this radar's application in the fuse. Because of the extraordinary property of non-atmosphere window millimeter wave, it can make fuse work covertly. The enemy spies and disturbs it difficultly. The atmosphere attenuation don't affect the natural work of millimeter wave fuse. So it is an important direction that non-atmosphere window millimeter wave short range radar is applied in the fuse.
