Abstract:

Radiowave propagation measurements at Edwards Air Force Base, CA are described. These measurements were made as part of the Flexible Interoperable Transceiver (FIT) Program. The objective of the measurements is to define communication link requirements at 440, 1360, and 1920 MHz. Simultaneous wideband measurements at three frequencies were made using fixed transmitters and a mobile fitted with a multi-channel receiver. The system measured the radio channel impulse response. Data outputs include delay spread and basic transmission loss. These parameters are compared at the three measurement frequencies to determine additional propagation impairments military systems will suffer due to frequency translation from 440 MHz to 1360 MHz and 1920 MHz.
