Abstract

The invention provides a radar actual measurement echo data processing method, electronic equipment and a storage medium. The method comprises the steps: obtaining radar actual measurement data, and generating a radar echo Doppler spectrum based on Fourier transform; estimating the average clutter-noise ratio of each distance unit of the radar echo Doppler spectrum, and obtaining a boundary based on the average clutter-noise ratio of each distance unit so as to divide the radar detection area into a short-range area, a medium-range area and a long-range area; and carrying out signal-to-noise ratio calculation in the short-range area, carrying out signal-to-noise ratio calculation in the medium-range area, and carrying out signal-to-noise ratio calculation in the long-range area. According to the invention, the radar echo area is divided, and the signal-to-clutter ratio, the signal-to-clutter-noise ratio and the signal-to-noise ratio of the short-range area, the medium-range area and the long-range area are calculated according to the dominant situation of different energies in the divided area, so that the situation that the signal-to-clutter ratio is inaccurately estimated due to the influence of the energies in different distance areas is avoided, and a foundation is laid for improving the accuracy of a radar detection performance evaluation result.

Description

technical field [0001] The present invention relates to the technical field of radar, in particular to a processing method, electronic equipment and storage medium for echo data measured by radar. Background technique [0002] Radar is an electromagnetic sensor used to detect and locate objects. Target information can be obtained from radar echoes, including distance, radial velocity, angular direction, size, and shape. Generally speaking, for a specific type of target, such as a certain radar cross-sectional area (RCS) value, the calculation of the detection power of a specific type of radar for such a target is mainly performed using the radar equation to evaluate whether the target can be detected. From the initial simple radar equation to the present, the radar equation incorporates different influencing factors, making the calculation of related parameters using the equation more accurate. In particular, the modern radar system incorporates a variety of new technologi...
