The invention provides a method for estimating flow rate by using a radar current measuring instrument, comprising the following steps: 1) measuring surface flow velocity; 2) calculating synthetic surface flow velocity; 3) calculating average flow velocity; 4) calculating flow rate. The present invention calculates the average flow velocity by establishing the corresponding functional relationship between the surface flow velocity and the average flow velocity, and does not use the Manning formula to calculate the average flow velocity. The present invention needs to measure less data when calculating the flow rate, avoids the inevitable error caused by the measurement to a certain extent, and reduces the cost and complexity required for calculating the flow rate. When the relationship between flow rate, more fitting functions can be used, which has good scalability.
