Ultra-wideband time-varying motion multi-system and multi-signal generation method

The invention discloses an ultra-wideband time-varying motion multi-system and multi-signal generation method. The method is a basis for constructing an electromagnetic environment test system, a target positioning and track test system and a signal playback system, and has the dynamic characteristics of time varying, multi-signal system, motion and the like. When a system test is carried out, parameters such as a time domain, an energy domain, a frequency domain, a modulation mode and a space domain need to be continuously adjusted. Ultra-wideband time-varying motion multi-system and multi-signal synthesis has three difficulties of large signal generation operation quantity, tedious editing and merging, discontinuous downloading and playing, incapability of real-time adjustment and the like. According to the ultra-wideband time-varying motion multi-system and multi-signal synthesis method based on single-signal independent configuration, an FPGA multi-channel signal generation structure and a multi-system an
