Cascaded fmcw radar with synchronized pll

Abstract

Provided is a cascaded FMCW radar, and more particularly, to a cascaded FMCW radar with a synchronized PLL. The cascaded FMCW radar includes a crystal oscillator generating a reference frequency signal having low-frequency characteristics, a cascade-array transceiver chip generating an output signal having high-frequency characteristics using the reference frequency signal through a signal generator provided therein, and an antenna transmitting the generated output signal to the outside in the form of an electromagnetic wave or receiving the electromagnetic wave from the outside.

Dependencies are inferred from the claim text.
