Embodiment Construction
[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0038] Step 1, the radar receiving scatterer returns a three-dimensional echo sequence containing pulse-distance-wave position.
[0039] Step 2, establish the distance-wave position coordinate system.
[0040] Convert the echo sequence into a grayscale image, and establish a distance-wave position coordinate system.
[0041] Step 3, select the range-wave position resolution unit.
[0042] Choose a point from the distance-wave position coordinate system, and form the distance-wave position resolution unit corresponding to the point.
[0043] Step 4, calculate the magnitude and phase linearity matrix.
[0044] Use the amplitude value formula to calculate the amplitude value of the selected range-wave position resolution unit;
[0045] The amplitude value formula is as follows:
[0046]
[0047] Among them, P k Indicates the amplitude value of the kth r...
