A target sensor is a device used to detect the presence of a target object. Target sensors are typically used in conjunction with a tracking system to track the movement of a target object. Target sensors can be used in a variety of applications, including military, law enforcement, and manufacturing.
Target sensors can be classified into two main types: active and passive. Active target sensors emit a signal and then detect the reflected signal from the target object. Passive target sensors do not emit a signal and instead detect the natural radiation emitted by the target object.
