Error Simulation Method of Interferometric Imaging Altimeter Based on Wavenumber Spectrum Analysis

Aiming at the error factors affecting the measurement accuracy of interferometric imaging altimeter, the error simulation method in this paper is carried out from the angle of wavenumber spectrum. The principle and process of simulation are given in this paper. And the main errors affecting the accuracy of measurement are analyzed and simulated which include: baseline inclination error, baseline length error, random noise error, sea state bias, dry tropospheric delay error, wet tropospheric delay error, ionospheric delay error, etc.
