Problems solved by technology

However, in the process of elevation inversion, they still use the processing method of the single-base model, and do not consider the special changes of the bi-base model, so it is not a good solution

Embodiment Construction

[0049] The one-station fixed bistatic interferometric SAR processing method provided by the present invention proposes a data processing method specially for one-station fixed bistatic interference for the bistatic special geometric model: this method is based on the traditional single-static model, The method of elevation inversion is improved to make it suitable for processing the interferometric data under the mode of one-station fixed bistatic, and obtain more accurate results. This method can invert the elevation information of the scene through data processing. Applies to bistatic interferometric processing techniques.

[0050] The method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0051] In this embodiment, the basic parameters of the SAR simulation system and the geometric configuration of the scene are basically as follows:

[0052]Satellite height: 630km

[0053] Satellite incid...

Abstract

The invention discloses a one-station fixed bistatic interference synthetic aperture radar (SAR) processing method, and belongs to the technical field of SARs. According to the one-station fixed bistatic interference SAR processing method, a data processing method special for one-station fixed bistatic interference is provided for a special bistatic geometric model, an elevation inversion method is improved to be applied to the processing of interference data in a one-station fixed bistatic mode on the basis of the conventional monostatic model, a more accurate result is obtained, and the elevation information of a scene can be inversed by data processing. The method is applied to a bistatic interference processing technology.

Description

technical field [0001] The invention relates to a one-station fixed bistatic interferometric SAR processing method, which belongs to the technical field of synthetic aperture radar. Background technique [0002] Synthetic Aperture Radar (SAR) is an all-weather, all-weather high-resolution microwave remote sensing imaging radar that can be installed on aircraft, satellites, spacecraft and other flying platforms. It has unique advantages in environmental monitoring, ocean observation, resource exploration, crop yield estimation, surveying and mapping, and military applications, and can play a role that other remote sensing methods are difficult to play. [0003] Compared with monostatic radar, bistatic radar has the advantages of flexible configuration, rich information acquisition, anti-interception and anti-interference due to the special configuration of bistatic radar. These advantages and application prospects have made bistatic radar more and more popular in recent years...
