An automatic (or aided) target recognizer (ATR) consists of two essential stages: detection and recognition. This chapter covers detection algorithms for literal imagery and ground targets, which are the most basic cases. There are a large number of other cases that aren’t covered. Other sensor types (such as vibrometer, high-range-resolution radar, ground-penetrating radar, LADAR, sonar, magnetometer, etc.) and other target types (such as buried landmines, ballistic missiles, aircraft, underground facilities, hidden nuclear material, etc.) require detection algorithms specific to those circumstances. However, the basic strategy covered here still applies.
