Title:
SYSTEM, APPARATUS AND DEVICE OF DOPPLER DETECTION AND RANGING
Document Type and Number:
WIPO Patent Application WO/2021/198759
Kind Code:
A1
Abstract:
In many applications such as automobiles on busy highways, if a lot of vehicles on road are equipped with Doppler radars or LIDARs to help improve driving safety, no matter human-driven or autonomous-driven, if the radars use same frequency, or LIDARS are modulated by signals of same frequency, avoiding interference among them is a hard task. Assigning distinct frequencies is one of the solutions, however not only it wastes expensive spectrum resource, but also the task itself to dynamically assign frequency to vehicles randomly coming together becomes a hard one to do. The disclosed invention of Doppler group sensor (including radar, LIDAR and sonar) will allow sensor devices to inherently work together using shared frequency without interfering with one another, without sacrificing performance, and without much increase in costs. Furthermore, this feature is achievable without having to involve higher layer protocols.
