Portable radar environment monitoring device for visually impaired human, has signal processing unit designed according to similarity criteria to examine existence of similarity between electrical signal sequence and sequence samples

摘要

The device (100) has a radar-front-end (102) formed to scan a spatial environment by sending radar radiation and to receive and output electrical signal sequences. A signal processing unit (112) is designed according to pre-defined similarity criteria to examine existence of similarity between an electrical signal sequence received from the radar-front-end and pre-recorded electrical signal sequence samples stored in a memory unit (116) i.e. environment database, which outputs output signals assigned to concerned sequence sample to an output unit (114) during existence of the similarity. An independent claim is also included for a method for monitoring environment with a portable radar environment monitoring device.
