The simulation of MMV fuze echo characteristics in rainfall based on Monte Carlo

To enhance the adaptability of millimeter wave (MMV) fuzes in rainy conditions, the attenuation and scattering impacts of rainfall was conducted. Furthermore, a mathematical model was formulated to study the characteristics of MMV fuze echo signals under rainfall environments, and the MMV fuzes echo signals are simulated based on the Monte Carlo method. The results show that rainfall leads to a substantial increase in the bottom noise of the echo signal, and the rainfall backward scattering signal mainly exists in the low-frequency region, but even in the heavy rain and rainstorm environment, the MMV fuze proximity ranging effect is basically unaffected. The results of the study can provide a reference basis for the adaptability of MMV fuze to complex environments.
