KEH-255 is K-Band transmitter and receiver developed by Nanoradar, a powerful comprehensive radar sensor, utilizing 1T2R radio frequency framework. By using advanced SiGe MMIC technology and supporting CW / FSK / FMCW modulation modes, KEH-255 can detect the velocity of moving targets, distinguish the direction and measure the range of static or moving targets etc. In addition, with dual receiving antenna, KEH-255 also has the function of angle measurement, and can accurately provide two-dimensional information of targets. It is widely used in the wide area surveillance and security, traffic monitoring, industrial control and other fields.
