Abstract: A radar system includes a radar transceiver device, which includes a transmitter front end circuit for transmitting a chirp signal towards an object. The radar transceiver device includes a receiver front end circuit for receiving the reflected chirp signal from the object. The radar transceiver device includes a voltage controlled oscillator (VCO) to generate a transmitted chirp signal. The radar transceiver device includes a mixer configured to generate four intermediate frequency output signals having different phases. The radar system includes a controller device, which includes a processor, and a memory for storing the intermediate frequency output signals and instructions for executing in the processor. The instructions cause the processor to generate a complex Fast Fourier Transform (FFT) result by performing a FFT of the intermediate frequency output signals while using zero-padding.
