Abstract

The invention provides an apparatus for real time displaying of images of a synthetic aperture radar. The apparatus comprises a format conversion unit, an input frame caching unit, an ARM communication unit, a frame caching control unit, a pretreatment unit, a picture frame caching unit, a video data integration unit and a video image display unit. Compared with traditional SAR real time image display apparatuses, the real time image displaying apparatus specially used for the synthetic aperture radar does not need intervention of a computer, and can directly convert real time image data of the synthetic aperture radar into formats of video images and carry out displaying.

Description

technical field

[0001] The invention relates to the technical field of digital image display, in particular to a device for displaying synthetic aperture radar images in real time. Background technique

[0002] SAR is an active high-resolution microwave imaging radar, which can acquire images of microwave scattering characteristics of ground objects all-weather and all-weather. Its excellent performance makes it widely used in military and civilian applications and plays an important role. Airborne SAR radar systems are generally equipped with a real-time imaging processor, which processes digitized echo data in real time, obtains two-dimensional images of ground objects, and displays them for reference by operators.

[0003] The real-time image display device is an important part of the real-time imaging processor. The structure of the existing real-time image display device is as follows: figure 1 shown. Generally, two implementation schemes are adopted: the first is t...
