Radar and Sensors AIAA 1 Robert Adams Angie Brooks
Defined RADAR Radio Detection and Ranging A system that uses radio waves to detect and determine the direction, distance, and/or speed of objects and map them SENSOR A device that responds to a physical stimulus and transmits a resulting impulse (as for measurement or operating a control)

Sensors Position Pressure Force Radar ( Some Examples from Honeywell…
Position Measures position of Flaps, engine nozzle, landing gear, and pilot input controls. This device is a Honeywell RVDT weighing in at 1/3 pound.
Pressure Measures gage, absolute and differential pressures. Used in bleed air, fuel, engine oil and hydraulic fluid pressures applications. Weighs about 5 oz without addition of fitting.
Force Used for pilot input measurements, servo- loop feedback, overload protection and payload measurement. Weighs 1.75 lbs Torque sensor weighs about 2 lbs.
Radar Sensor Informs the pilot that the enemy has radar pointed at them. An example is the ALR-69. It is a basic fuzz buster for the military. Has a 3 by 9 in Cathode Ray Tube. Cost less then $15000 per unit and weighs approximately 42 lbs.
