| Abstract: | Because the conventional ultra wideband(UWB) radar imaging algorithm cannot meet the demand in the capability of multiple targets detection,a novel UWB radar imaging algorithm based on the near field radiation theory of dipole is presented.On the foundation of researching the principle of a time domain imaging algorithm,the back projection(BP) algorithm is derived and analyzed.Firstly,the far field sampling data are transferred to the near field sampling data by using the near field radiation theory of dipo... |
| Keywords: | ultra wideband(UWB) back projection(BP) algorithm dipole finite-difference time-domain(FDTD) method. |
