For phase i, amsi proposes to identify and establish the technical feasibility of various advanced acoustic array concepts. three generic approaches are currently identified: 1) optimize the sensor design (i.e., directional sensors, etc.), 2) optimize hydrophone/ group/array geometry (i.e.,… More

For phase i, appliedmeasurement systems, inc. (amsi) proposes to identify and establish the technical feasibility of a self-contained hull potential measurement system for underway ships. three generic approaches are currently identified: 1) measurement sensor selection, 2) electronic/software… More

The dolphin has a unique sonar capability by which it produces high-frequency clicks. The dolphin is able to vary both the frequency content and the repetition rate of the echolocation clicks. The goal of the combined Phase I and Phase II project is to model the dolphin sonar and to design,… More

Under the current U.S. Navy budget constrained environment it is desirable to get added functional performance from existing sonar systems. One such case is the need to provide instantaneous bearing ambiguity resolution for threat torpedoes at tactically significant ranges via U.S. Navy Surface… More

When waveguides of high power radar systems are installed in corrosive environments gaps tend to form at the joints. These gaps change the characteristic impedance of the waveguide, causing reduced system efficiency and potential damage to the radar. An indication of these gaps are arcs generated… More

The new joint mission scenarios and stealth interdiction objectives for the U.S. Navy have resulted in the need for improved sensor systems for operations in the littoral environment. A High Frequency Towed Array (HFRA) sonar system, operating in the same frequency band as hull mounted systems,… More

Significant advances have been made over the past few years in all optical arrays. Low cost optical sensors have been produced and demonstrated along with optical telemetry capable of multiplexing many sensors onto a single optical fiber. Although the new optical sensors and telemetry designs … More

Special Operations Forces (SOF) require a real time display of appr opriate data to allow the helmsman to access the damage potential to his cargo (equipment/personnel) and support his decision relative to speed and course selection when operating in rough water. Furthermore, maintenance support… More
