What is a characteristic of passive homing systems?

The characteristic of passive homing systems being able to detect energy emitted from the target is a defining feature of this technology. Passive homing relies on capturing signals or emissions that are naturally produced by the target, such as heat, radar signals, or other forms of electromagnetic radiation. Unlike active systems that emit their own signals for guidance, passive systems are designed to remain undetected while identifying the location and movement of the target based solely on the energy that it radiates.

This capability allows for stealthy engagement, as the weapon does not reveal its presence by actively searching or transmitting signals. This can enhance the effectiveness of the system in various combat scenarios, making it safer for the user while increasing the chances of successfully tracking and engaging a target without alerting it to the incoming threat.
