8 Radome Design Guidelines
8.1 Effect of Radome on the Performance of mmWave Sensors
•
Radar waves are reflected on the radome boundary
• Loss of total power radiated or received by the radar
• The reflected wave enters the receiving channel, affecting the isolation between the transmitting and receiving channels
• Reflection may deteriorate the standing wave of the antenna, further affecting the antenna gain
• Radar waves will suffer loss when propagating in the medium. Theoretically, the higher the frequency, the greater the loss
• Electromagnetic waves are refracted to a certain extent when passing through a medium
• Affects the radiation pattern of the antenna and thus the coverage of the sensor
8.2 Design principles of radome
8.3common material
• Before designing, understand the material and electrical characteristics of the radome
