| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The precise knowledge of the antenna phase center is of great importance for the signal processing and accurate ranging using a radar system. This paper proposes an experimental method to determine the frequency-dependent location of antenna phase center. A two-dimensional survey is carried out to acquire the transmission signal at different offsets. From the offset-dependent phase of each transmission frequency component, the frequency-dependent location of phase center is derived. A laboratory test using a cavity-backed planar equiangular spiral antenna, which is a common kind of frequency-independent and dispersive antenna, demonstrates the effectiveness of the proposed method. | |
