77Ghz is mainly used for forward warning systems, while 24Ghz is used for rear and side.
Compared with 24Ghz, 77G has a wider detection range, higher accuracy, smaller units, and lower power consumption. Although it provides better performance, the technology is limited to leading companies such as Bosch, Continental, and Defu. Xinjingfu is concentrating on research and development and is about to mass-produce 77G radar systems.
