The invention belongs to the technical field of radar detection, and relates to a method and application for correcting Doppler velocities obtained by scanning radar in distributed soft target velocity field detection. The method comprises the following steps: (S1) performing radar scanning to obtain Doppler velocities of each position point on the distributed soft targets, and estimating plane velocities of each position point on the distributed soft targets on a radar scanning plane; (S2) estimating accelerations of each position point on the distributed soft targets according to the material derivative based on the plane velocities and Doppler velocities of each position point; and (S3) correcting the velocities of each position point on the distributed soft targets according to the velocity correction formula. The invention also provides an application process for acquiring correction speeds of each position point on the wake of the aircraft by using the Doppler velocity correctionmethod, and estimating the vortex core trajectory of the aircraft wake vortex according to the correction velocities of each position point. By correcting the Doppler velocity field by the invention,the accuracy of wind speed estimation in the field of meteorological detection can be effectively improved.
