Abstract
An image generating device for a radar includes a receiving module configured to receive a radar signal from an antenna and process the radar signal to generate an echo, an edge image generator configured to generate an edge echo image based on the echo acquired at a first time instance, a projected image generator configured to generate a projected echo image based on the echo acquired at a second time instance, and a superimposition generator configured to superimpose the edge echo image on the projected echo image based on the first and second time instances, to generate a superimposed echo image.
Claims19
An image generating device for a radar, comprising:
- processing circuitry configured to:
- receive a radar signal from an antenna and process the radar signal to acquire an echo at a first time instance and an echo at a second time instance;
- generate an edge echo image based on the echo acquired at the first time instance;
- generate a projected echo image based on the echo acquired at the second time instance;
- superimpose the edge echo image on the projected echo image based on the first and second time instances, to generate a superimposed echo image;
- store the edge echo image as a previous pooled echo image;
- generate a current transparent image of the projected echo image using edge extraction;
- and
- combine the previous pooled echo image with the current transparent image to generate a current pooled echo image, such that the current pooled echo image includes a plurality of extracted edges of a plurality of previous echoes acquired at a corresponding plurality of previous time instances, and use the current pooled echo image for superimposing on a next echo image acquired at a time instance next to the second time instance.
An image generating method for a radar, comprising:
- receiving a radar signal from an antenna;
- processing the radar signal to acquire an echo at a first time instance and an echo at a second time instance;
- generating an edge echo image based on the echo acquired at the first time instance;
- generating a projected echo image based on the echo acquired at the second time instance;
- superimposing the edge echo image on the projected echo image based on the first and second time instances, to generate a superimposed echo image;
- storing the edge echo image as a previous pooled echo image;
- generating a current transparent image of the projected echo image using edge extraction;
- and
- combining the previous pooled echo image with the current transparent image to generate a current pooled echo image, such that the current pooled echo image includes a plurality of extracted edges of a plurality of previous echoes acquired at a corresponding plurality of previous time instances, and use the current pooled echo image for superimposing on a next echo image acquired at a time instance next to the second time instance.
A non-transitory computer readable medium having stored thereon computer-executable instructions which, when executed by a computer, cause the computer to:
- receive a radar signal from an antenna;
- process the radar signal to acquire an echo at a first time instance and an echo at a second time instance;
- generate an edge echo image based on the echo acquired at the first time instance;
- generate a projected echo image based on the echo acquired at the second time instance;
- superimpose the edge echo image on the projected echo image based on the first and second time instances, to generate a superimposed echo image;
- store the edge echo image as a previous pooled echo image;
- generate a current transparent image of the projected echo image using edge extraction;
- and
- combine the previous pooled echo image with the current transparent image to generate a current pooled echo image, such that the current pooled echo image includes a plurality of extracted edges of a plurality of previous echoes acquired at a corresponding plurality of previous time instances, and use the current pooled echo image for superimposing on a next echo image acquired at a time instance next to the second time instance.
