The invention discloses a ground seismic source excitation system based on a microwave radar and a seismic data acquisition method, and the system comprises a microwave radar sensor which is used for transmitting a microwave signal, forming an induction scanning area around, and is triggered based on the shielding of the microwave signal when a seismic source body touches the ground; the time service module synchronously records and stores the grounding time of the seismic source body on the basis that the microwave radar sensor is triggered; the positioning module is used for calculating, recording and storing grounding coordinates of the seismic source body based on the scanning data; and the wireless communication module synchronously transmits a wireless pulse signal to the seismological observation system based on the triggering of the microwave radar sensor, so that the seismological observation system synchronously carries out seismic data acquisition. Timing and/or positioning of seismic source body l
