The radar device for a vehicle according to an exemplary embodiment of the present invention includes an antenna part including a plurality of transmitting antennas and a plurality of receiving antennas, the antenna part being formed of array antennas; a signal processor for detecting a target by processing a radar signal and a reflected signal transmitted and received through the antenna part; and a feeding part for correcting phases of the radar signal and the reflected signal through a feeding line connecting the antenna part and the signal processor, wherein the signal processor corrects a phase of a noise signal based on the phase information of a feeding line designed such that a false target corresponding to the noise signal incoming is detected at a specific angle.

Radar device for vehicle and control method thereof

According to a radar system according to these embodiments, by mounting a radar antenna, an RF device, and a controller on an upper face and a lower face of a circuit board, the size and the cost can be reduced by decreasing the number of constituent components, and the reliability and the durability can be improved by discharging heat generated in the circuit board to the outside.

Radar system and radar sensing system having the same

The present disclosure relates to a radar system and a transmission apparatus therefor, including a signal generator for generating a first signal; a phase adjuster configured to include a plurality of input ports and at least one output port, to generate a second signal by adjusting the phase of the first signal according to an input port through which the first signal is transmitted among the plurality of input ports, and to output the generated second signal to an antenna unit; and a port selector configured to select at least one of the plurality of input ports of the phase adjuster according to an identification code and to transmit the first signal through the selected input port so that a transmission signal radiated through the antenna unit is phase inverted or formed in a pattern corresponding to the identification code, so that interference by the other radar system can be minimized, and the accuracy, reliability and frequency efficiency of the radar system can be improved.

Radar system and transmission apparatus therefor

A vehicle radar. In the vehicle radar, a high-pass filter is disposed on a signal line connecting a transmitting chip and a receiving chip, the signal line allowing a local oscillation signal to be transferred therethrough. The high-pass filter prevents noise from being introduced through the signal line, along which the local oscillation signal is transferred. This prevents the accuracy of detection from being lowered by low-frequency noise generated from the interior of the vehicle radar. The high-pass filter connected to the signal line is embodied as a variety of configurations, thereby providing a structure able to effectively suppress low-frequency noise while maintaining the existing structure of the vehicle radar.

Radar having structure able to suppress low-frequency noise

Embodiments disclosed herein relates to a radar device, and more particularly, to a radar device having a structure that reduces the influence of an internal reflected wave, which is capable of preventing a target sensing performance from being deteriorated by a reflected wave reflected within the radar device, while having a cover structure that is capable of protecting an antenna from the outside.
