Introduction

NXP provides a total system solution with next-generation embedded radar-based products that include the Qorivva MPC577xK MCU

and 77 GHz packaged radar front-end chipset for both low- and high-end radar modules. This pairing delivers a complete embedded radar

system for automotive designs. Our total solution advances automotive safety by enabling vehicles to sense potential crash situations.

This radar solution provides long- and mid-range functionality, allowing automotive systems to monitor the environment around the vehicle

to help prevent crashes.

A typical radar module consists of a transmit solution (Tx), VCO and three-channel receiver IC (Rx), along with an MCU. The chips are

connected via the local oscillator signal, around 38 GHz. The individual control of each chip is implemented by a serial peripheral interface

(SPI) bus. The main controller and modulation master is a single MCU with integrated high-speed analog-to-digital converters (ADCs) and

appropriate signal processing capability, such as fast Fourier transforms (FFTs).
