Title:
METHODS AND APPARATUS FOR DISTRIBUTED, MULTI-NODE, LOW-FREQUENCY RADAR SYSTEMS FOR DEGRADED VISUAL ENVIRONMENTS
Document Type and Number:
WIPO Patent Application WO/2019/032165
Kind Code:
A3
Abstract:
Methods, apparatus, systems and articles of manufacture are disclosed for distributed, multi-node, low frequency radar systems for degraded visual environments. An example system includes a transmitter to transmit a radar signal. The example system includes a distributed network of radar receivers to receive the radar signal at each receiver. The example system includes a processor to determine a first range and a first angular position of a background point based on return time, wherein the first range and the first angular position are included in first data; determine a second range and a second angular position of the background point based on doppler shift, wherein the second range and the second angular position are included in second data; determine a refined range and a refined angular position, wherein the refined range and refined angular position are included in third data, and generate a radar map based on third data.
