Abstract
A radar image processing device performs determination of a pixel including a ghost image and changes the value of the pixel which is determined to include the ghost image on a radar image the focus of which has been changed.
Claims13
A radar image processing device comprising:
- processing circuitry to perform a process of:
- inputting a radar image and changing a focus of the radar image;
- determining a pixel including a ghost image from the radar image the focus of which has been changed by;
- changing a value of the pixel that has been determined to include the ghost image on the radar image the focus of which has been changed;
- and
- normalizing a pixel amplitude in the radar image,
- wherein the process determines an image including a ghost image from radar images, the amplitude of a pixel of which is normalized and the focus of which is changed.

A radar image processing device comprising:
- processing circuitry to perform a process of:
- inputting a radar image and changing a focus of the radar image;
- determining a pixel including a ghost image from the radar image the focus of which has been changed;
- and
- changing a value of the pixel that has been determined to include the ghost image on the radar image the focus of which has been changed,
- wherein the process converts a signal of the radar image from a time domain to a Doppler frequency domain, and changes the focus of the radar image so that a phase correction amount of the signal in the Doppler frequency domain does not contain a component proportional in a Doppler frequency direction.

- determining a pixel including a ghost image from the radar image the focus of which has been changed;
- and
- changing a value of the pixel that has been determined to include the ghost image on the radar image the focus of which has been changed,
- wherein the process changes the focus of the radar image to multiple focuses, and
- the process specifies information related to a focus that reduces blur of the ghost image on a basis of a change in a pixel value in radar images that are changed to have the respective multiple focuses and determines the pixel including the ghost image on a basis of the specified information related to the focus.
