Public Service Communications • State of California backbone network. • Law enforcement systems - state, county, city - mobile, relay, and base station equipment. • Forest service units. • Fire and government emergency systems - county and city operations. • Common carrier networks - telephone, data, television services - remote area voice links. Specialized Services • Space tracking and monitoring facilities (Goldstone area). • Railroad hump radars. These system categories are in the frequency range cited for the file retrieval and are susceptible to SPS power densities listed in Table 4.2. The character of functional degradation induced into particular major equipment categories deployed near the candidate Mojave site is indicated in Table 4.3. Those functional systems include high priority operations that encompass relatively large geographic areas around the periphery of the rectenna site. The elements of performance degradation cited for the functional systems represent average overall operating modes and geographic range. For example, instrumentation radar systems detection and tracking performance includes operation over a full hemisphere coverage, and the range of cross section magnitudes for military target vehicles (e.g., tactical fighter and reconnaissance aircraft, target drones). Track score variations include low elevation angle modes where the accuracy degradation and loss of lock probabilities expand by greater margins because of propagation factors. The communications system degradation cited includes single channel, and frequency and time multiplexed units operated by the military test ranges, the State of California, local county and municipal governments, and resource control and service industries. The performance degradation is related to operational compromises of the military instrumentation and systems used in operational testing at China Lake, George Air Force Base, Edwards Air Force Base, and the ECHO facility; and the command/control and other communications facilities associated with the resource management operations by utilities and local governments.
