Description
JY-L Multi-spectral Camouflage Net
Radar and Infrared Effect Test Report
I. TECHNICAL SPECIFICATIONS
1. Visible Lights Stealth
Working Band: 0.4~0.76μm
In visual range, the camouflage nets match the nature background perfectly.
2. Near Infrared Stealth
Working Band: 0.76~1.20μm
In near IR range, the camouflage nets match the nature background perfectly.
3. Thermal Infrared Stealth
Working Band: 3~5, 8~14μm
Temperature of the camouflaged target can be reduced by more than 10℃when target temperature is higher than the ambient temperature of 20℃
4. Radar Stealth
Working Band: K、X、C、S、L (2-40GHz)
Reflection rate of radar wave measured in anechoic chamber is -30dB, attenuation of RCS figure of the target measured in radar test range is 10dB
II. Explanation of Test Result on the Sample net of JY-L Multi-spectral Camouflage Net
1.Near Infrared ：
a．Photographic Test
From following pictures, the object covered with JY-L camouflage net showed the same near infrared image as surroundings.
b． On Near IR spectrum reflection test, the object covered with JY-L showed very similar spectrum graph with natural green plants.
2. Radar reflection attenuation test results
a. Chart 1, Radar reflection attenuation
L Band | S Band | C Band | X Band | Ku Band | |
Frequency range | 2GHz | 2－4GHz | 4－8GHz | 8－12GHz | 12－18GHz |
Average reflection | －3.37dB | －14.2dB | －10.5dB | －19.1dB | －15.3dB |
b. Radar ground RCS Test
The red lines are the radar reflection graph of the object without camouflage net. The black lines are the radar reflection graph of the object covered with JY-L camouflage net. The following picture shows that the black lines laid much below the red line, which means the radar reflection is lower if coverd with the camouflage net.
3. Thermal Image and thermal reflection shield test
There are 6 different points with different temperatures within a range of 15~75OC. picture 1 is thermal object without camouflage net. Picture 2 is thermal image of object covered with JY-L camo net. For high temperature objects, the camouflage net can reduce at least 10℃
