Radar set, AN/PPS–15(V)2, is a battery–powered, solid state, coherent doppler, line–of–sight, very short range ground surveillance radar.

The radar set is used to detect and locate moving personnel and vehicles (targets) under various conditions of terrain, visibility, and weather. Target detection and identification are accomplished by operator's recognition of characteristic sounds in the electrical headset.

An alarm lamp and speaker provide automatic visual and audible indications when a moving target is detected. Indicators provide digital bearing and range information. The following paragraphs in this chapter describe the various uses and capabilities. This chapter, Annex A, provides the data necessary for the operational and unit level maintenance.

Terrestrial Search and Scanning. The radar set can be operated as a hand–held radar, or it may be mounted on a tripod for local or remote operation. The radar set can be rotated manually and electrically through 6 400 mils (360E) in azimuth and manually from –600 mils (–34E) to +400 mils (+23E) in elevation when mounted on the tripod. Automatic bearing scanning is provided, with two bearing scanning widths 800 mils (45E) and 1600 mils (90E), available for selection by the operator.

Detected moving objects will produce an audible sound in the headset and audible and visual alarms from the automatic alarm circuits.

This manual also contains both doctrine and training guidance on these subjects. Part One addresses map reading and Part Two, land navigation.

The appendixes include a list of exportable training materials, a matrix of land navigation tasks, an introduction to orienteering, and a discussion of several devices that can assist the soldier in land navigation.

This manual applies to every soldier in the Army regardless of service branch, MOS, or rank.
