Zusammenfassung:A signal generation and transmission system includes a modulator and an RF transceiver. The RF transceiver includes a voltage-controlled oscillator, a power divider, a low-pass filter, a low-noise amplifier and a mixer. The voltage-controlled oscillator receives a signal from the modulator and produces a frequency modulated continuous wave signal. The power divider receives the frequency modulated continuous wave signal from the voltage-controlled oscillator. The low-pass filter receives the frequency modulated continuous wave signal from the power divider. The low-noise amplifier receives, amplifies and transfers a target echo signal. The mixer combines the frequency modulated continuous wave signal from the power divider with the echo signal of target from the low-noise amplifier so that the two signals are added up or subtracted from each other in a frequency band.
