In this paper, a signal simulation model for millimeter wave radiometer of terminal sensing ammunition is proposed to address the problem in accurately modeling and simulating the millimeter wave radiometer signal of terminal sensing ammunition under high dynamic and complex target background conditions. And a partition method is proposed based on the idea of solving integration to calculate the intersection area between the field view of millimeter wave radiometer and the targets. Finally, simulation is conducted to generate the output signal of millimeter wave radiometer under different conditions, including multi-objects, horizontal wind and the oscillation of the parachute. The simulation results show that the proposed method can effectively address numerical simulation of millimeter wave radiometer signals under high dynamic and complex target background conditions. The study of this paper can be used as a reference for improving the target recognition algorithm of terminal sensing ammunition and enhancing the performance of sensors.
