The electromagnetic track gun projectile velocimetry radar usually work in a strong magnetic field environment. Based on the analysis of the basic structure and working principle of Doppler radar for the measurement of electromagnetic rail gun and projectile velocity, the electromagnetic compatibility problems of projectile velocity radar in strong magnetic field are discussed, including the characteristics of electromagnetic radiation of electromagnetic rail gun and the principle of strong electromagnetic shielding , Requirements and design considerations. Using Doppler radar velocity measurement method, a set of practical testing system of projectile velocity inside the bore of the electromagnetic rail was designed to measure the projectile velocity in the electromagnetic borehole in real time, accurately and accurately, thus solving the urgent problem in the research of the electromagnetic gun.
