RADAR INTERFEROMETER AND METHOD OF TARGET POSITION ESTIMATION USING THE SAME

摘要

A radar interferometer and a method for estimating a target position are provided to estimate a target distance and a target incident angle from a radar to the target by using phase information of a signal received at an antenna. An antenna unit(200) includes a first antenna combination(110), a second antenna combination(120), a third antenna combination(130) and a fourth antenna combination(140). The first antenna combination and the second antenna combination are arranged with different intervals by using two antennas in an x axis in a three dimensional space. The third antenna combination and the fourth antenna combination are arranged in parallel with different intervals by using two antennas in a y axis in a three dimensional space. A position estimating unit is connected to the antenna unit. The position estimating unit estimates respective incident angles of the x axis and the y axis and the target distance.
