Handling the cross-node phase noise in a non-coherent radar system

摘要

A radar system and method for detecting an object include a first node having a first transmitter and a first receiver and a second node having a second transmitter and a second receiver. The second receiver receives a first receive signal from an object from a first transmission by the first transmitter, the first receive signal including a first phase noise having a first delay, and the first receiver receiving a second receive signal from the object from a second transmission by the second transmitter receives, wherein the second received signal includes a second phase noise with a second delay. A processor processes the first transmission, the first received signal, the second transmission, the second received signal to eliminate the cross-node phase noise and to estimate a location of the object relative to the radar system based on the first delay and the second delay.
