Analysis of rain effects on millimeter wave fuze ground-echo characteristics
Journal of physics(2023)
摘要
Abstract Due to the wide antenna beam of the ground fuze and the similar size between the millimeter wave wavelength and raindrop particles, the ground millimeter wave fuze will suffer from serious rainfall interference in the rainfall environment, which greatly affects the accurate ranging performance of fuze. In this paper, we establish ground target echo signal model in the rain condition, and analyze the effects of target distance, rainfall and frequency on the ground millimeter wave fuze in rain. The results provide theoretical basis of anti-rain interference for millimeter wave fuze.
