Abstract

The disclosure relates to a radar control device and method. Specifically, a radar control device according to the disclosure comprises a transceiver transmitting a transmission signal through each transmission channel including a first transmission channel and a second transmission channel, receiving a reception signal of the transmission signal, reflected by a target, through each reception channel including a first reception channel and a second reception channel, and receiving temperature sensing information from a temperature sensor and a controller controlling to determine relative phase compensation information resultant from compensating a relative phase between the first reception channel and the second reception channel into a relative phase at a preset reference temperature, based on the reception signal and the temperature sensing information.

Dependent claims

A radar control device, comprising:

a temperature sensor for detecting a temperature of the radar control device;
a transceiver transmitting a transmission signal through each transmission channel including a first transmission channel and a second transmission channel, receiving a reception signal of the transmission signal, reflected by a target, through each reception channel including a first reception channel and a second reception channel, and receiving temperature detection information from the temperature sensor;
and
a controller, which is implemented as an electronic control unit (ECU), configured to be controlled to determine relative phase compensation information between the first reception channel and the second reception channel, which is a relative phase between the first reception channel and the second reception channel at a reference temperature,
wherein the controller determines a first slope and a second slope regarding a phase variation according to a temperature change in each of the first reception channel and the second reception channel, based on a slope determination equation,
wherein the controller determines the relative phase compensation information between the first reception channel and the second reception channel based on a relative phase compensation equation, the first slope, and the second slope,
wherein the relative phase compensation equation is set to determine compensation weight information by multiplying the first slope minus the second slope by the reference temperature minus a detected temperature x, and determine the relative phase compensation information as a sum of a relative phase between the first reception channel and the second reception channel at the detected temperature and the compensation weight information,
wherein the reference temperature is determined as a temperature detected consistently for a predetermined period of time or a temperature detected at the highest frequency for a predetermined period of time.
