TF-I Lomber lens reflector is allowed to be used in several octaves with a wavelength greater than 2 cm. Its radar reflection cross-sectional area is inversely proportional to the square of the wavelength, and the reflection angle is correspondingly unchanged.
The radar reflection cross-sectional area shown in Table 1 refers to the corresponding data when the frequency is 9375mhz. Refer to table 2 for other frequency band data.
