| Abstract(in English) | Array-factor (AF) theory is the widely and commonly method used to calculate and design array antenna pattern. Assuming that each element of array is a small point source, the combined electromagnetic field created due to these sources in far-region is obtained by AF. In this paper, we will make a explanation and tutorial discussion for some specific radar applications concentrated on AF, which has both simplicity and versatility. The practical four topics are prepared: First is an application to near-field to far-field transformation for evaluating antenna and RCS. Second, it is shown that radar image can be obtained by repeating transmitting and receiving from each element of array. This is considered an imaging method based on Fourier theory as same the so-called SAR, but the resolution in short-range target is more excellent than SAR. Furthermore, as a third topic, we explain the electronic beam scanning method for 3-dimensional conformal array. Finally, we discus the mechanism of MIMO virtual array as a fundamental study to combine to the conformal technology. |
