BY ORDER OF THE AIR FORCE INSTRUCTION 13-101
SECRETARY OF THE AIR FORCE 3 MAY 1994

Space, Missile, Command, and Control

EVALUATION OF GROUND RADAR SYSTEMS

____________________________________________________________________________________________________

This instruction implements AFPD 13-1, Theater Air Control Systems. It provides guidance and procedures for the Air Force program for evaluating ground surveillance radar systems (fixed and mobile). Affected systems include Joint Surveillance, North Warning, Tethered Aerostat Radar, and Theater Air Control Systems.

SUMMARY OF CHANGES

This revision aligns the instruction with AFPD 13-1 and incorporates the requirements, information, and procedures formerly in AFR 55-58. It reorganizes text and changes requirements and procedures. It designates Air Combat Command (ACC) as the Air Force's executive agency for the overall ground radar evaluation program.

1. Major Commands (MAJCOM). MAJCOMs that operate ground surveillance radar systems will:

2. Air Combat Command. ACC is the executive agency for the USAF radar evaluation program. In addition to responsibilities noted in paragraph 1, ACC will:
3. Terms:
3.1. Ground Radar Systems Evaluations. These provide information on optimum configuration of adjustable and selectable features (software and hardware), assist in radar systems siting, and assess the interaction and integration of radars into higher order network environments. Types of evaluations include baseline, commissioning, special, periodic, and system.

3.1.1. Baseline Evaluation. This evaluation determines system capabilities and limitations, including airspace coverage. It provides the basis for a continual appraisal of radar performance to determine system capability. Baseline evaluations are tailored to individual radar sites and missions. They include such factors as the effects of weather and terrain on detecting and tracking performance. The baseline evaluation provides a performance data base, operational parameters, and airspace coverage as a basis for developing a periodic evaluation program.
3.1.1.1. Mobile radar systems require this type of evaluation only at their in-garrison location (unless a deployed location becomes fixed).
3.1.1.2. The 84 RADES should conduct an initial baseline evaluation as soon as possible after a unit completes acceptance testing and resolves major exceptions. The system should be operationally stable and properly connected with its control center when applicable. The operating organization should request a baseline evaluation in accordance with paragraph 3.1 before using the radar for aircraft control.
3.1.1.3. The 84 RADES should reverify previously baselined radars every 10 years or, if deemed necessary, following major repairs, major modifications, or permanent radar resiting or as specified in US Standard Flight Inspection Manual Procedures.
3.1.2. Commissioning Evaluation. This is a baseline evaluation performed prior to commissioning. It determines specific operating parameters and procedures maintained by the operating organization to sustain maximum performance.
3.1.3. Special Evaluation. This evaluation is performed in lieu of a baseline evaluation to:

3.1.4. Periodic Evaluation. This evaluation is performed on previously baselined radars. It detects deviations from established standards based on radar performance documented during a baseline or commissioning evaluation and long term trend analysis. A process of sampling and analysis of radar system products, the periodic evaluation assesses system effectiveness and deterioration in mission capability.
3.1.5. System Evaluation. This evaluation determines how well multiple sensors integrate into a central facility or system and how well the system performs its mission.

4. Requesting Evaluations. Submit evaluation requests to 605 TESTS/TSH, 203 West D Avenue, Suite 400, Eglin AFB FL 32542-6867. Additionally, send an information copy to 84 RADES, 7976 Aspen Avenue, Hill AFB UT 84056-5846. Quarterly, or as otherwise previously agreed, MAJCOMs and field operating agencies will update current year needs. Request unforeseen evaluation needs using the same format as annual projections and quarterly updates. Non-government organizations will request evaluations through HQ USAF/XOOOD. Requests will be prioritized according to attachment 2.

5. Manpower Requirements:
5.1. Military Personnel Assignments. HQ AFMPC will assign evaluation personnel at the 84 RADES to stabilized three-year tours of duty and give them special experience identifiers in accordance with the provisions of AFI 36-2101, Classifying Military Personnel (Officer and Airman), formerly AFR 35-1.
5.2. Skill Levels. Enlisted personnel assigned to the 84 RADES will have a minimum five-level skill Air Force specialty code to ensure they are qualified to evaluate radar systems.
