| Zusammenfassung: | PURPOSE:To measure an antenna pattern during actual use by operating the transmitting and receiving module in an electronically controlled antenna at practical-use temperature. CONSTITUTION:Transmission and reception are switched as well as in actual use through microwave switches 11 and 12 and circulators 13 and 14 similar to units in the actual use. Transmitting antenna patterns of an antenna pattern measuring transmitter 9 and an electronically controlled antenna 4, and measuring horn antenna 3 and antenna pattern measuring pulse receiver 10, and receiving antenna 3 and transmitter 9, and antenna 4 and receiver 10 are measured. Those transmitting and receiving antenna patterns are measured at the same time by putting transmitting and receiving modules in the electronically controlled antenna in operation at actual use temperature to measure the electronically controlled antenna pattern in the actual use. |
