Define the term "target recognition."

The term "target recognition" refers specifically to the process of identifying and classifying an object based on its attributes, such as its radar signature. This is an essential capability in various fields, including military applications, where distinguishing between friend or foe can determine mission success. Target recognition involves analyzing various signatures that an object may emit or reflect, allowing for accurate identification. This process is critical for situational awareness, enabling operators to make informed decisions based on the type of targets they encounter.

In contrast, capturing images of an object relates more to imaging technologies rather than the specific identification and classification aspects of target recognition. Measuring the distance to an object relates to range finding and does not encompass the classification component. Tracking an object over time pertains to monitoring movements rather than identifying what the target actually is. Therefore, the correct interpretation of target recognition closely aligns with the process of identification and classification based on distinct signatures, making the second option the most accurate representation of the term.
