Page 4: The Impact Of Radome On Modules
Rd Series Module Radome Design Guide V1.1.0 . The impact of radome on modules Signal attenuation: The material and structure of the radome will attenuate the propagation of radar signals. Depending on the materials and media of the radome, the propagation energy loss of radar waves is different, which will affect the detection range and accuracy of the radar to some extent. - Page 5 Rd Series Module Radome Design Guide V1.1.0 It can effectively protect the antenna from harsh environments and improve the reliability and performance of the radar system. Here are some factors to consider in radar module radome design: Material selection: The material of the radome should have good weather resistance, ...

Page 6: Radome Height And Thickness Design
Rd Series Module Radome Design Guide V1.1.0 In short, the design of the radar module radome should comprehensively consider factors such as material, shape, size, transparency, waterproof, dustproof and anti-corrosion to ensure that the radome can fully protect the radar antenna and will not have a negative impact on the performance of the radar module. -
Page 7: The Distance Between The Outer And Inner Walls Of The Radome: D
Rd Series Module Radome Design Guide V1.1.0 The ideal height is an integer multiple of the radar half-wavelength (0/2) in the air. Maintaining an appropriate distance between the antenna and the inner surface of the radome can effectively reduce the reflection effect caused by the radome. When the reflected electromagnetic wave is different from the emitted electromagnetic wave When consistent, this effect will be minimized. -
Page 8: Common Material Designs For Radomes
Rd Series Module Radome Design Guide V1.1.0 is inversely proportional to the dielectric constant of the material. The thickness of the radome can be calculated by the following formula. The meaning of each parameter in the formula: d is the thickness of the radome; n is a positive integer;... - Page 9 Rd Series Module Radome Design Guide V1.1.0 and low temperatures. Radomes usually need to withstand corrosive environments such as acid rain and salt spray, so the materials should have good anti-corrosion properties and be able to resist erosion by corrosive substances. When choosing a material, you also need to consider its weight and cost.

Page 14: Installation Environment Requirements
Rd Series Module Radome Design Guide V1.1.0 Due to differences in target size, status, RCS, etc., the target distance accuracy will fluctuate; at the same time, the maximum distance will also fluctuate slightly. When there are multiple 24GHz band radars, please do not have beams facing each other and install them as far away as possible to avoid possible mutual interference. -
