Embodiment Construction

[0021] refer to figure 1 , a planar integrated waveguide array antenna proposed by the present invention includes: a first antenna array 1 , a second antenna array 2 and a carbon fiber reinforced plate 3 . The antenna adopts a circularly polarized wave transmission and reception method that can resist weather interference such as clouds, fog, and rain.

[0022] The first antenna front 1, the second antenna front 2 and the carbon fiber reinforced plate 3 are arranged in parallel, and the backs of the first antenna front 1 and the second antenna front 2 face each other to realize simultaneous scanning, searching and tracking of targets on both sides. The carbon fiber reinforced plate 3 is located between the first antenna front surface 1 and the second antenna front surface 2 and bonded to the two to improve the interception rate of the antenna. Both the first antenna array 1 and the second antenna array 2 use SIW (Substrate integrated waveguide, planar integrated waveguide) sl...

Abstract

The present invention proposes a planar integrated waveguide array antenna, which is light in weight, low in cost and good in performance, and is conducive to improving the monitoring performance of airborne early warning airborne radar, which includes: a first antenna array, a second antenna array and a carbon fiber reinforcement plate ; The first antenna front, the second antenna front and the carbon fiber reinforced plate are arranged in parallel, the back of the first antenna front and the second antenna front are opposite, and the carbon fiber reinforced plate is located between the first antenna front and the second antenna front And fit them together to improve the antenna intercept rate; both the first antenna front and the second antenna front include 84 horizontally arranged SIW slot antenna elements, 168 T / R components, and two vertically placed SIW Feed network, sum difference network; the output terminals of 168 T / R components are respectively connected to the two ends of 84 SIW slot antenna elements, and the output terminals of each 1 / 42 SIW series feed distribution network are connected to 42 T / R components component's input and feeds it.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a planar integrated waveguide array antenna. Background technique [0002] AEW (Air Early Warning, air command and early warning aircraft), which integrates the functions of command, intelligence, communication and control systems, is an effective means to obtain air supremacy in modern warfare. Long-distance search and longer warning time can improve the combat effectiveness of the Air Force. Therefore, all major military powers have invested heavily to continuously improve their combat effectiveness. [0003] The existing fixed-wing early warning aircraft are suitable for deployment on land or large aircraft carriers. Most of these early warning radars are mounted on modified large transport aircraft or passenger aircraft, and their take-off and landing distances are hundreds of meters or even longer, so they are only suitable for land Alert or carried on a supercarrier.
