| Abstract: | The three dimensional imaging idea of millimeter radar is briefly introduced. The principle and method of radar imaging are analyzed in detail. The theory to extract angular error is described and the realization of millimeter radar's digital phase comparator and extracting method of angular error's sign are discussed. The way to make use of three channel range profiles to obtain the three dimensional image is derived and the range azimuth, range elevation and range azimuth elevation images of real airplane are shown. |
