The invention provides a method for processing radar measured echo data, electronic equipment and a storage medium. The method includes: acquiring radar measured data, and generating a radar echo Doppler spectrum based on Fourier transform; estimating the radar echo Doppler spectrum The average clutter-to-noise ratio of each range unit, and based on the average clutter-to-noise ratio of each range unit, the dividing line is obtained to divide the radar detection area into short-range, medium-range and long-range areas; signal noise in the short-range area Calculate the signal-to-noise ratio in the medium-range area, and perform the signal-to-noise ratio calculation in the long-range area. The present invention divides the radar echo area, and then according to the situation that different energies occupy a dominant position in the divided area, the signal-to-clutter ratio, signal-to-noise ratio, and signal-to-noise ratio are respectively calculated for the short-range area, the mid-range area, and the long-range area. In order to avoid the inaccurate estimation of signal-to-clutter ratio due to the influence of energy in different distance areas, it lays the foundation for improving the accuracy of radar detection performance evaluation results.
Description
technical field [0001] The invention relates to the technical field of radar, and in particular, to a processing method, electronic equipment and storage medium of radar measured echo data. Background technique [0002] Radar is an electromagnetic sensor used to detect and locate objects. The information of the target can be obtained from the radar echo, including distance, radial velocity, angular direction, size and shape. Generally, for a specific type of target, such as corresponding to a certain radar cross-sectional area (RCS) value, to calculate the detection power of a specific type of radar to such a target, the radar equation is mainly used for calculation to evaluate whether the target can be detected. From the original simple radar equation to the present, the radar equation incorporates different influencing factors, making it more accurate to use the equation to calculate the relevant parameters. In particular, modern radar systems incorporate a variety of ne...
