Abstract: A signal processing system includes a transmission module and a receiving module. The transmission module generates and transmits a transmitted radio frequency signal according to a data signal and a first spread vector. The transmission module includes a spread spectrum unit, a digital-to-analog converter and a mixer. The spread spectrum unit generates a spread spectrum signal according to the data signal and the first spread vector. The digital-to-analog unit generates an analog signal according to the spread spectrum signal. The mixer mixes the analog signal and a carrier signal so as to generate the transmitted radio frequency signal. The receiving module receives a received radio frequency signal and a second spread vector so as to generate a spectrum despread signal and generate object detection information data accordingly. The received radio frequency signal is generated by having the transmitted radio frequency signal reflected by a measured object.
