RF SIGNAL TRANSCEIVER IN RADAR SYSTEM AND METHOD THEREOF

摘要

An RF signal transceiver in radar system and method thereof are provided to extend the bandwidth of the chirp signals and increase the resolution of the radar systems. The source(100) produces the chirp signals to the constant cycle. According to cycle the chirp signals, the RF transmitter(310) produces the transmission radio frequency chirp signals by upconverting in the other RF(radio frequency) subband. The RF receiver(320) makes the receiving radio frequency chirp signals corresponding to the transmission radio frequency chirp signals by the down-conversion(down convert). The RF transmitter comprises a plurality of the BPFs(band pass filters), a plurality of local oscillators, and the switch and the mixer.
