Problems solved by technology

[0009] Aiming at the problems and deficiencies in the above-mentioned prior art, the object of the present invention is to provide a method for processing radar data using a dynamic clutter map. A clutter map control method with a freezing coefficient is adopted to solve the problems of aircraft and vehicles. The problem that moving objects may be filtered out as fixed targets due to low speed or stop driving reduces the false alarm rate of radar detection

Embodiment Construction

[0027] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should understand that following specific embodiment is only for illustrating the present invention and is not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand the present invention Modifications in various equivalent forms fall within the scope defined by the appended claims of the present application.

[0028] see figure 1 and figure 2 As shown, the present invention discloses a radar echo trail display system and display method.

[0029] Among them, the display system includes:

[0030] The radar echo information receiving module 1 is used to obtain the echo data Vn and the video frame memory address P(X, Y) corresponding to the echo according to the current radar echo information;

[0031] The video frame memory reading module 2 is used to read the data Vo of the v...

Abstract

The invention discloses a system and method for displaying radar echo wake. Through increasing zone bits for data in a video storage device, different colors of the radar echo and wake are displayed; the defects that the radar echo is relatively dense, and the echo and the wake are difficult to be distinguished at the long afterglow display state are solved effectively; and the running direction or the motion trend of a radar target can be distinguished well.

Description

technical field [0001] The invention relates to the technical field of radar video display processing. Background technique [0002] Explanation of terms: [0003] PPI: Radar plane position display, also known as distance and azimuth display, which displays the echo in the azimuth and distance of the target through signals such as radar echo and azimuth. [0004] Radar echo: The electromagnetic wave emitted by the radar is scattered by the target during the propagation process, and then the part of the electromagnetic wave received by the radar receiver. The radar echo appears as a series of bright spots on the PPI display. Usually, the brightness of these points indicates The strength of the radar echo can measure the azimuth and distance of the target according to the position of the bright spot on the screen. [0005] Trail: Refers to a series of radar echo images displayed on the PPI display from a certain time ago. [0006] On the radar PPI display, through the displ...
