Aberdeen Proving Ground (APG): The APG Standardized Test Site is located within a secured range area of the Aberdeen Proving Ground. The Aberdeen Area of APG is located approximately 30 miles northeast of Baltimore at the northern end of the Chesapeake Bay. The Standardized Test Site encompasses 17 acres of upland and lowland flats, woods and wetlands.

• Calibration Lane (0.30 acres)

The calibration portion of the test site consists of at least nineteen (19) lanes. This area contains 14 standard munitions items buried in six positions, with representation of clutter, at various angles and depths to allow demonstrators to calibrate their equipment. A wire hoop gives a standard signature to compare to the signature the detection instrument is receiving. If an installation has site-specific munitions that are not part of the Standardized Target, extra calibration lanes can be added.

• Ground Truth for APG Calibration Grid (58kb XLS)
• Repository Database Calibration Ordnance (22kb XLS)
• Blind Test Grid 0.50 acres

The APG Blind Test Grid (BTG) consists of 400 grid cells. The center of each blind grid cell contains either munitions, clutter, or nothing

• Open Field 10.00 acres

The Open Field area provides the demonstrator with a variety of realistic scenarios essential for evaluating sensor system performance. The scenarios and challenges found on this Open Field area consist of a gravel road, wet areas, dips, ruts and trees. Vegetation height varies from 15 to 25 centimeters. Other challenges that may be found on an open field site include electrical lines, swales, stone pads/roads, and metallic fencing that test the capabilities of the platform systems or hand held detectors.

Recently the Open Field area was reconfigured to emulate typical impact area conditions. The Open Field area is now divided into four subareas (legacy, direct fire, indirect fire and challenge):

• Open field (legacy)
  The legacy subarea contains the same wide variety of randomly-placed munitions that were present in the open field prior to the January 2008 general reconfiguration of the site.
• Open field (direct fire)
  The direct fire subarea contains only three munition types that could be typically found at an impact area of a direct fire weapons range. Munitions and clutter are placed in a pattern typical for these munitions.
• Open field (indirect fire)
  The indirect fire subarea contains only three munition types that could be typically found at an impact area of an indirect fire weapons range. Munitions and clutter are placed in a pattern typical for these munitions.
• Open field (challenge)
  The challenge subarea is easily reconfigurable used to meet the specific needs and requirements of the demonstrator or the program sponsor. Any results from this area will not be reported in the standardized scoring record.
• Scenario 1. Moguls 1.30 acres

Mogul Area — The Mogul Area consists of two areas (the rectangular or driving portion of the course and the triangular section with more difficult, non-drivable terrain). The rectangular section includes six (6) test lanes, which incorporate a slope challenge, 0.61m and 0.91m moguls, 0.61m and 0.91m slanted moguls, and vibration lanes. This section of the course is designed for testing vendors' vehicles' abilities to traverse adverse terrain (vehicle must minimize damage to terrain) and to check accuracy of sensor equipment when subjected to vibration and offset angles created by rough terrain. The triangular section incorporates more intense moguls and terrain, which can be traversed only by foot using hand held or pushed sensor devices. A series of craters (as deep as 0.91m) and mounds (as high as 0.91m) encompasses this section. As rainwater fills the craters, the water serves as another challenge to the demonstrators.

• Scenario 2. Wooded Area 1.34 acres

Wooded Area (for APG only) — This area consists of cleared woods (tree removal with only stumps remaining), partially cleared woods (including all underbrush and fallen trees), and virgin woods (i.e., woods in natural state with all trees, underbrush, and fallen trees left in place).
