Electronic warfare (EW) is one of the crucial aspects of modern warfare. EW receivers are passive systems that receive emission from various platforms that operate in the relative vicinity. The received signals are typically analyzed to obtain valuable information about characteristics and intentions of various elements that are presented in …
Read More »Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. At present, 90% of the sea-going naval ship are diesel-powered. To achieve the safe upper limit for global warming of 1.5 degrees Celsius, ‘all ships designed and built today must operate in …

DARPA, is proposing a new Mosaic Warfare strategy for evolving multidomain battlefield. Dr. Timothy Grayson, Director of the Strategic Technology Office is advocating for a “system of systems” approach that he’s calling mosaic warfare: the ability to piece together different systems to build new overarching warfighting capabilities. DARPA’s Strategic Technology …

The performance of electronics degrades as temperature increases from the ambient temperature. The temperature of a device increases when the device is on since no system operates at 100% efficiency. Output power is not equal to the power fed to the device, and the difference between this is power loss. …

Photography measures how much light of different color hits the photographic film. However, light is also a wave, and is therefore characterized by the phase. Phase specifies the position of a point within the wave cycle and correlates to depth of information, meaning that recording the phase of light scattered …
