An aircraft detecting device is commonly referred to as an "aircraft radar" or "radar system." These systems are used to detect and track aircraft in the sky, providing information on their position, altitude, and speed. Other related technologies include transponders and ADS-B (Automatic Dependent Surveillance–Broadcast), which enhance situational awareness for air traffic control and pilots.

A device for detecting underwater objects is typically called a sonar device. Sonar uses sound waves to detect and locate objects underwater by measuring the time it takes for the sound waves to bounce off the object and return to the device.
It's called a "Motion Detector"!
Radar
Its called that Climbing - in relationship to just after takeoff it's called "climbing out"
A device that pushes a ship is typically called a "propeller," which creates thrust by rotating and pushing water backwards. For aircraft, this device is also referred to as a "propeller" when used, but aircraft can also utilize jet engines, which propel the aircraft by expelling exhaust gases at high speed. Both devices are crucial for enabling movement in their respective vehicles.
One way to measure airspeed is to use a device called a pitot tube.
e-nose
None. The megapixels are in the detecting device. e.g. a camera, a CCD device.
The rotating device that propels a ship is called a "propeller," while in aircraft, it is also referred to as a "propeller," or in some cases, "turbofan" or "jet engine" for jet-powered aircraft. Propellers work by converting rotational motion into thrust, allowing vessels to move through water or air.
IFF (identification of friend and foe device) will detect the enemy aircraft. Radar system also plays role in this operation.
