)2 D(@N EYFIEP1GH~TCZ6 why using phase compenation twice ? TBIQL8PR)L}KQ@(H53MHOVT

Xiangyu-Gao commented 10 months ago

The first compensation is for RangeData and the second compensation is for DopplerData and both of them were not compensated.

hujinxiangwd commented 3 months ago

in equation pha_com = exp(-1i pi ...) Why use pi instead of 2*pi ?

Xiangyu-Gao commented 3 months ago

the compensation equation originally should be: pha_com = exp(-1i 2 pi (detout(1,pick_idx)-fft_Vel/2-1) / fft_Vel / 2.) 2 is canceled out in the equation
