Applied Signal Technology, Inc. (AST), founded in 1984, provides advanced digital signal processing products, systems, and services in support of intelligence, surveillance, and reconnaissance (ISR) for global security. We provide processing of both man-made and naturally occurring signals. The processing of man-made signals includes communications intelligence (COMINT) and electronic intelligence (ELINT). The processing of natural signatures includes the use of sonar, radar, magnetic, and chemical sensors to detect changes in the environmental phenomenology. Our primary customer is the United States Government.
COMINT derives intelligence from telecommunications signals. Our COMINT signal collection equipment consists of sophisticated receivers that scan through potentially thousands of cellular telephone, microwave, ship-to-shore, and military transmissions in the radio frequency (RF) spectrum with the goal of collecting certain specific signals. Our COMINT signal processing equipment uses advanced software and hardware to evaluate characteristics of the collected signals and selects those most likely to contain relevant information.
ELINT derives intelligence from signals associated with weapons systems. Our investment in ELINT is directed toward the development of equipment for the collection and processing of weapons systems signals. This equipment will be able to scan the radar bands associated with weapons systems and determine the type of system and its precise location for battlefield characterization and force protection. The equipment will also analyze the command and control signals associated with these weapons systems to provide information about battlefield readiness.
Sensor signal processing observes changes in physical phenomena that can provide an indication of activities of concern to global security. Examples of these phenomena are detection of chemicals that might be used for explosive devices or the detection of sub-terrain ferrous materials that might indicate an underground facility for weapon manufacturing. Our sensor processing equipment provides automatic detection of physical abnormalities in both marine and terrestrial environments.
