The invention provides a method, a device and equipment for determining loss angle tangent of a medium and a storage medium. The method comprises the steps that based on a preset screening rule, multiple pieces of radar data obtained from an array radar are screened, multiple pieces of target radar data are obtained, and the radar data comprise multiple pieces of first sub-data corresponding to different sampling points; for each sampling point, performing average quadratic sum processing on first sub-data in the target radar data corresponding to the sampling point to obtain target sub-data; obtaining first target data according to the multiple pieces of target sub-data; performing correction processing on the first target data to obtain corrected first target data; performing unit conversion on the corrected first target data to obtain second target data; according to the change curve of the amplitude of the second target data, obtaining the slope of the change curve; and obtaining a loss angle tangent parameter value of the medium according to the slope and a radar equation.
Description
technical field [0001] The present disclosure relates to the technical field of loss tangent measurement, and more particularly, to a method, apparatus, device and storage medium for determining the loss tangent of a medium. Background technique [0002] The loss tangent can characterize the loss degree of the medium to the electromagnetic wave (such as radar signal), that is, the attenuation degree of the electromagnetic wave in the medium (such as the lunar soil). The larger the loss tangent, the greater the attenuation of the medium to the electromagnetic wave, and the shallower the penetration depth of the electromagnetic wave. [0003] In the process of realizing the concept of the present disclosure, the inventor found that the related art has at least the following problems: the accuracy of the loss tangent of the medium determined by the array radar is low, resulting in poor accuracy of the detection depth of the radar. SUMMARY OF THE INVENTION [0004] In view of...
