RADAR SYSTEM FOR VEHICLE AND OPERATING METHOD THEREOF
First Claim
1. A radar system for a vehicle, comprising:
- a radar which is located around the principal vehicle to detect a target vehicle which threatens driving of the principal vehicle as a target,wherein the radar includes;
a transmission antenna which transmits a signal for detecting the target vehicle;
a reception antenna which receives a reflective signal for the transmitted signal;
a communication module which transmits a high frequency signal through the transmission antenna;
a converting unit which converts the reception signal which is received through the reception antenna into a digital signal; and
a signal processing unit which generates a detection signal to detect the target vehicle, in accordance with a speed, a yaw rate of the principal vehicle and the digital signal, applies the detection signal to the communication module, and analyzes the digital signal which is converted in the converting unit to trace the target vehicle.
