Multi-target three-dimensional echo simulation method and device, terminal and storage medium

The invention belongs to the technical field of radar echo simulation, and particularly relates to a multi-target three-dimensional echo simulation method which comprises the following steps: acquiring first information which comprises the number of to-be-simulated targets and the number of to-be-simulated frames; for each frame, calculating echo data of each target in the frame; superposing the echo data of each target in the frame to obtain a digital echo matrix of the frame; and acquiring digital echo matrixes of all frames to obtain the multi-target three-dimensional echoes. According to the method, three-dimensional digital echoes of multiple targets and multiple frames can be simulated at the same time, various boundary conditions of an algorithm are fully simulated, the digital echoacquisition complexity is reduced, and thus algorithm debugging is facilitated. 本发明属于雷达回波模拟技术领域，尤其涉及一种多目标三维回波模拟方法，包括：获取第一信息，其中，所述第一信息包括待模拟目标个数和待模拟帧数；对于每一帧，计算该帧中各个目标的回波数据；将该帧中各个目标的回波数据叠加，获得该帧的数字回波矩阵；获取所有帧的数字回波矩阵，得到模拟的多目标三维回波。
