Figure 17. Impact of the radome-to-sensor distance on the radiation pattern (H-plane). Amplitude is stated in one
direction (Tx or Rx side). For Radar Loop Gain (RLG) the values will be doubled.
It is not recommended to place the cover directly on the sensor. Figure 18 shows the radiation pattern
on the H-plane when the cover (ABS plastic sheet) is located on top of the sensor. In comparison with
Free Space, there is around 3 dB loss on both max. power and total radiated power for this case.

direction (Tx or Rx side). For Radar Loop Gain (RLG) the values will be doubled.
