Rapid Assessment Method of Radar Dynamic Accuracy Based on Real-time Conversion of Accuracy Indexes

In order to improve the efficiency of radar dynamic accuracy assessment, firstly, aiming at the problem that the original accuracy statistics method based on error grouping has low automation and can only be applied to post-processing, a radar instantaneous accuracy estimation method based on median is proposed under the condition that the data acquisition frequency is not less than 20Hz, which simplifies the relevant process of accuracy statistics; Then, a double threshold accuracy rapid assessment method is given. The instantaneous accuracy of radar is evaluated in two steps in the measurement process by using two thresholds: accuracy index and over standard rate; Finally, aiming at the decline of the applicability of typical accuracy indexes in other cases or when they are directly used to evaluate the instantaneous accuracy of radar, a concept of real-time equivalent conversion of radar accuracy indexes is proposed. These works provide a reference method for rapid assessment of radar dynamic accuracy. The test under the measured data verifies the effectiveness of the proposed method.
