Abstract
Implementations of the present disclosure relate to a radar receiver for a real-valued analog RF radar signal. The radar receiver comprises a quadrature mixer circuit configured to generate, from the real-valued analog RF radar signal, a complex-valued analog signal comprising an inphase (I) signal component and a quadrature (Q) signal component, an analog polyphase filter configured to filter the I- and Q-signal components of the complex-valued analog signal to generate filtered I- and Q-signal components, and an analog-to-digital converter coupled to an output of the analog polyphase filter. The radar receiver is configured to convert only one of the filtered I- and Q-signal components from the analog to the digital signal domain.
