Title:
RADAR DEVICE
Document Type and Number:
Japanese Patent JP2022045714
Kind Code:
A
Abstract:
To provide a radar device that is able to suppress deterioration in reception performance even when the length of wiring for distributing a reference signal to a distributively arranged module or an influence of an external environmental change is significant.SOLUTION: In a radar device 1 in which a millimeter wave transmission module 10 and a millimeter wave reception module 21 connected by a connection cable 113 are distributively arranged, at least one of a transmission channel and a reception channel is multi-channeled; the millimeter wave transmission module 10 includes a transmission circuit 102 that generates a radar signal using a reference signal REF and a trigger signal TRIG transmitted from the millimeter wave reception module 21; a feedback signal of the trigger signal TRIG is input to the millimeter wave reception module 21; the millimeter wave reception module 21 includes a TDC 112 that detects a delay time between the trigger signal TRIG and the feedback signal, and the delay time is corrected based on the delay time.SELECTED DRAWING: Figure 1
