Example Embodiment
[0040] In the following, a method for rapid denoising of radar data based on spatial modeling technology of the present invention will be described in detail with reference to the accompanying drawings and embodiments.
[0041] Such as figure 1 As shown, the rapid denoising method for radar data based on spatial modeling technology of the present invention reads radar data such as Radarsat-2, and then performs calibration processing and multi-view processing successively, and then uses multi-directional reciprocal operation to perform filtering. noise. It includes the following steps:
[0042] Step 1. Data reading
[0043] Read radar data such as Radarsat-2 satellite data. In this embodiment, the radar data format is a geo-referenced fine resolution product, the polarization mode is HV, and the working band is C band, that is, the wavelength is 5.6 cm.
[0044] Step 2. Calibration processing
[0045] Obtain the radar data of the scene through the radar equation, so that the radar rem...
