FMCW Radar System Design Using Scenario Modeling

Applikationsberichte

Introduction

According to government reports, thousands of people annually lose their lives and millions more have been injured due to car accidents all over the world [1]. That’s a prime reason why scientists and engineers are working on automotive applications, trying to develop automotive radar systems to reduce human casualties from car collisions. As the result of this market demand, various radar systems, such as adaptive cruise contro (ACC), stop-and-go, blind spot detection (BSD), lane change assist (LCA), and rear crash

warning (RCW), are now widely used in vehicles.

Automotive radar based on a frequency modulated continuous waveform (FMCW) [2] is one

technology that is today widely used. Unlike pulse radar, FMCW Radar using continuous

wave modulation can avoid high peak-to-average power ratio (PAPR) in transmission,

which simplifies the design process for antennas and RF components like power

amplifiers. Consequently, an automotive radar system based on this technology offers

more advantages, such as good performance with simplified RF components, small size,

light weight, and low cost.
