Problems solved by technology

[0009] 2) The length and width of the metal base plate structure are fixed, and the width can be adjusted by splicing multiple pieces. In the height direction, only various types of shielding screens required by different heights can be produced, which is inconvenient to use and uneconomical in cost
[0010] 3) After the outdoor field test, the shielding screens need to be collected, gathered and stored after the daily work. The existing shielding screens are too large in size and quantity, occupy too much space for storage, difficult to transport, and often cannot be maintained properly. There are rapid failure of absorbing materials, short life and high maintenance costs

Embodiment 1

[0032] The present invention is a method for forming a radar wave absorbing material shielding screen, and the steps are:

[0033] S1. Use long block-shaped flat plate absorbing materials as back-to-back materials;

[0034] S2. Install a pyramid absorbing material of the required length in the direction of the incoming electromagnetic wave, and adjust the direction of the pyramid of the material;

[0035] S3. Use non-metallic strings to bundle the pyramid wave absorbing material and the backrest material into one;

[0036] S4. Expand the width and height on both sides and above to form the required radar absorbing material shielding screen.

[0037] After the test, untie the non-metallic string, separate the pyramid wave absorbing material and the backing material, pack it, and transport it back to the room for storage.

[0038] The non-metallic thin rope is a nylon rope.

Embodiment 2

[0040] Shielding screen forming method: use long flat plate absorbing materials as the backrest, and install a single pyramid absorbing material with required length (such as 500mm×500mm or 400mm×00mm, etc., according to specific needs) in front. , adjust the direction of the material pyramid, and use non-metallic strings to bundle the material and the backrest into one through the cone bottom gap of the pyramid absorbing material to form the required radar absorbing material to block the screen-based unit.

[0041] "Flexible" width and height adjustment: according to the actual task needs, add the pyramid wave absorbing material from both sides, "flexible" adjust the width of the wave absorbing material shielding screen (the width of the backrest is also increased according to the actual needs), and then increase the angle from the upper height direction. Cone and backrest, "flexibly" adjust the height and size of the shielding screen of the absorbing material to meet the tech...

Abstract

The invention discloses a method for forming a shielding screen of radar wave absorbing material. The steps are as follows: stacking a long block flat wave absorbing material as a back-to-back material; adding a corner-cone wave absorbing material with a required length in the direction of incoming electromagnetic waves; Adjust the direction of the material pyramid; use non-metallic strings to bundle the pyramid absorbing material and the backing material into one; expand the width and height on both sides and above to form the required radar absorbing material shield; The metal string is untied, the pyramid absorbing material and the backrest material are separated, boxed, and transported back to the room for storage. The beneficial effects of the invention are as follows: the shielding screen is all made of radar wave-absorbing materials, which has good wave-absorbing effect and low background echo; the width and height of the shielding screen can be adjusted flexibly, and the forming method is simple and practical; ; It can be flexibly decomposed and stored, the storage space requirement is small, and the use and maintenance are cost-effective.

Description

technical field [0001] The utility model belongs to the technical field of radar target characteristic testing and testing, and relates to the improvement, optimization and innovation of a wave-absorbing material shielding screen forming method used in the background reduction treatment of an outdoor test site. Background technique [0002] The rapid development of modern radio technology and radar detection technology has greatly enhanced the ability to search and track targets in war. Traditional combat weapons are increasingly threatened, and the low detectability of targets An essential and important means of asymmetric operational advantage. However, the development and improvement of the ability of low detectable characteristics of targets cannot be separated from repeated iterative optimization and verification tests. Outdoor field static test is a relatively common method for the detection of characteristics of large-scale full-object radar targets at home and abroad...
