Since Radars use radio wave in the detection process, the Radar front ends are related to electronic circuits that operate with high-frequency signals. Depending on the purpose of applications, these frequencies range from hundreds of MHz up to hundreds of GHz. The design of Radar sensors involve the development of PCBs and software around building blocks such as radar front ends, amplifiers, PLL & loop filters, ADC and microcontrollers, data interfaces and passive elements.

Radar sensors typically share a similar structure as shown in Figure 1. Some building blocks used in Radar sensors are described here.
