Phase delay in rotated PPP. (
a) Phase delay with no inclination among reference and object wavefronts. The solid blue line is for the proposed phase delay estimation, dashed orange curve is for phase delay from the paper []. (
b) Phase delay dependence on
inclination angle between reference and object wavefronts. The solid red line is phase shift,
because of inclination on
, a dotted orange curve is phase delay with
, a dash-dot purple curve is phase delay with
, and dashed orange curve is phase delay with
.
