Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings.

[0045] Such as figure 1 As shown, the radar image display method based on layered display of the present invention includes the following steps,

[0046] Step (A), after the radar image display system receives the clutter background image, it constructs the clutter point data object according to the data point angle, distance and amplitude attributes, and stores it in the real-time memory at the same time, and the radar image display The system defines this part of the memory as a clutter background layer, which specifically includes the following steps,

[0047] (A1), create a memory data area for clutter data storage according to the configuration file of the radar image display system;

[0048] (A2), construct the clutter point data object according to the angle, distance and amplitude attributes of the received clutter background image, specifically: the received c...

Abstract

The invention discloses a radar image display method based on hierarchical display. The method comprises the following steps: defining a clutter background layer; creating a clutter background image buffer area; extracting memory data required by the clutter background image layer, compressing the memory data, and writing the compressed memory data into the created clutter background image bufferarea; defining as a moving target signal layer; creating a moving target signal image buffer area; taking out memory data required by the moving target signal layer, mapping, and writing into a movingtarget signal image buffer area; wherein the clutter background image written into the clutter background image buffer area is used as a background image layer, the moving target signal image writteninto the moving target signal image buffer area is used as a display control image layer, and the two images are combined for image drawing. The layered display design and the image buffer technologyare adopted, radar image display can be simply and conveniently carried out in display control with low configuration of the processor and the video card of the radar detection system, and good application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of radar image display and transmission, in particular to a radar image display method based on layered display. Background technique [0002] The real-time display of radar image is one of the important components of the radar system, which has the characteristics of high refresh rate, high real-time performance and high resolution. Conventional radar image display is usually composed of clutter background image and moving target signal. The clutter background image can display the background image formed by ground clutter, sea clutter, etc., and the moving target signal can be displayed in real time and track the moving target. ,Support display and control click to select and display the properties of the selected moving target signal (such as speed, distance, amplitude, etc.). [0003] The difficulty of radar image display is that the data points of the clutter background image usually exceed one million...
