RADAR SIGNAL PROCESSING DEVICE AND RADAR SIGNAL PROCESSING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18223708 titled 'RADAR SIGNAL PROCESSING DEVICE AND RADAR SIGNAL PROCESSING METHOD

Simplified Explanation

The patent application describes a radar signal processing device that includes several components to improve the accuracy of target object detection and measurement.

  • The device forms beams using reception signals.
  • It compensates for phase within a certain frequency range.
  • It generates an image of each beam by applying Fourier transform in an azimuth direction.
  • The device identifies the position of a target object based on the generated image.
  • It calculates the power of each beam at the position of the target object.
  • It computes the antenna gain of each beam at the position of the target object.
  • The device measures the angle on the target object using maximum likelihood estimation by comparing the power of each beam with the antenna gain of each beam at the target object's position.


Original Abstract Submitted

A radar signal processing device includes: a forming unit to form beams by using reception signals; a compensation unit to compensate for a phase within a range frequency; a generation unit to generate an image of each beam by applying Fourier transform in an azimuth direction to the beams (with phases compensated; an identification unit to identify a position of a target object based on the image; a calculation unit to calculate power of each beam represented by the image of each beam at a position of the target object; a computing unit to compute an antenna gain of each beam at a position of the target object; and an angle measurement unit to measure angle on the target object by performing maximum likelihood estimation of comparing the power of each beam with the antenna gain of each beam at the position of the target object.
