An apparatus for real time displaying of images of a synthetic aperture radar

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...

Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, in the drawings or descriptions of the specification, similar or identical parts all use the same figure numbers. Implementations not shown or described in the accompanying drawings are forms known to those of ordinary skill in the art. Additionally, while illustrations of parameters including particular values ​​may be provided herein, it should be understood that the parameters need not be exactly equal to the corresponding values, but rather may approximate the corresponding values ​​within acceptable error margins or design constraints.

[0022] The present invention proposes a device for real-time display of synthetic aperture radar images, which gets rid of the intermediate link of a computer,...
