A Sensor is an electronic device that is used to measure some sort of physical parameters (e.g. temperature, pressure, light intensity, etc). The output of an electronic sensor is an electrical signal that is either analog or digital. Processing the sensor’s output can be done in hardware (using discrete electronic elements) or in software (using some sort of microcontrollers or MPUs).
Sensors are being employed in a wide range of applications. Some of the applications include Automation, Robotics, Embedded Systems, Computers, Smart Cars, Avionics, Satellites, Smart Homes, Smartphones, Smart Watches, Energy plants, Remote Sensing, and Communications.
Electronic sensors are essential for various military surveillance, intelligence, ordinance, and combat technologies. Information is critical to military success, and the data is gathered through sensors on a range of platforms, including aircraft, unmanned aerial vehicles, weapon systems, ground vehicles and even from soldiers in the field through smart wearable devices.
By monitoring strategic defence as well as civilian installations such as parliament, airports, metro etc. and will provide much greater protection to our armed forces as well as civilian population.
Sensors have become an integral part of military systems and the performance needs of all military vehicles, equipment and related systems. Sensors are used in flight controls, propulsion, environmental monitoring, weaponry controls, indicators, communications and so on.
Intelligence, surveillance, and reconnaissance (ISR) capabilities enable Militaries to be aware of developments related to adversaries worldwide and to conduct a wide variety of critical missions, both in peacetime and in conflict. ISR is carried through a networked sensors operating in space, cyberspace, air, land, and maritime domains. The vision of sensors is to enable complete situational awareness under all weather, day/night, and beyond-line-of-sight and through natural and man-made obstructions.
Military and defence systems include drones, spacecrafts, missiles, military vehicles, ships, marine systems, satellites and rockets. These systems work in the harshest of environments during normal as well as combat operations.
Sensors are also used in battlefield surveillance systems for the conduct of modern warfare. These are deployed on land, aerial platforms, in space and underwater, to keep a 24×7 watch over a particular targeted zone. Radars /SAR /GMTI have emerged as most effective sensors for long range detection and tracking of military targets under all weather, day/night conditions.
