Joint detection and estimation

Joint detection and estimation involve simultaneously identifying whether a specific condition or event has occurred (detection) while also determining precise details about that condition (estimation). For example, in radar, the system detects if an object is present (detection) and then estimates its position and speed (estimation). Combining both processes in a single approach improves accuracy and efficiency, especially in noisy or uncertain environments. Essentially, it's like recognizing if someone is at the door and then figuring out exactly who they are and where they’re standing, all in one integrated process.
