摘要
| 描述 | Low quality photo of a U.S. Navy Lockheed EP-3A Orion (BuNo 149673) of air test and evaluation squadron VX-1 Pioneers in 1983. This aircraft was used in the "EMPASS" project, the "Electromagnetic Performance of Air and Ship Systems" (EMPASS) Project. The airborne system consisted of radio frequency (RF) receivers and antennas with special relays and interface units which allowed a UNIVAC 1830A computer to interrogate and control them. Aircraft position, RF signal, and system status measurements were recorded digitally on magnetic tape while operator displays were provided for some immediate data analysis and system monitoring. The flight crew were all Navy personnel, while the electronics and computer equipment operators were civilians. A typical mission would carry a crew of ten people. The a/c was capable of mapping three-dimensional antenna patterns of live, operational transmitters. Recordings made during flight were returned to Dahlgren Naval Base (Virginia) for analysis and plotting of antenna patterns. |
