I. INTRODUCTION 


Applied Research Laboratories, The University of Texas at Austin 
(ARL:UT), was awarded Contract N00140-76-C-6487, sponsored by New London 
Laboratory, Naval Underwater Systems Center (NLONLAB NUSC), effective 
1 June 1976. Some of the work under this contract represents a follow-on 
effort to previous work sponsored by NLONLAB NUSC under Contract 
N00140-74-C-6316. 

The work under Contract N00140-76-C-6487 was originally divided into 
six task areas that focused on technical support in areas of sonar 
technology. 

I. AN/FQM-10(V) Sonar Test Set Field Support 

II. Transducer Repair Facility Test Site Field Support 

III. AN/WQM-5 Sonar Test Set Field Support 

IV. Special Purpose Passive Sonar Systems Support 

V. Sonar Instrumentation Test and Evaluation 

VI. Study of Towed Line Array Acoustical Testing at Transducer 

Repair Facilities 

Additional tasks were added by contract modifications, as follows. 

VII. AN/SQM-( ) Sonar Noise Measuring Set Development (Mod P00019) 

VIII. AN/WQM-5( ) Sonar Test Set Development (P00019) 

IX. Sonar Dome Maintenance Documentation Support (P00019) 

X. AN/BQQ-5 Power Supply Development (P00019) (follow-on work 
under Contracts N00024-77-C-6035 and similar effort under 
N00123-79-C-0459) 

XI. AN/BQQ-6 Test Instrumentation (P00035) 

XII. AN/WLR-12 Calibration (P00033)

III. SONAR INSTRUMENTATION AND EVALUATION 

A. AN/GQM-2 Transducer Test Set 

Daring this quarter, the following updated documentation and software 
for the AN/GQM-2 Transducer Test Set were forwarded to the appropriate 
facilities: 

1. User Calibration Procedure, AN/GQM-2 Transducer Test Set, 
TL-EA-80-3, 22 February 1980, 

2. AN/GQM-2 Operate Overlay, and 

3. AN/GQM-2 Operate Tape, Version 02 (5/1/80). 

B. AN/SQM-( ) 

No work was performed on the AN/SQM-( ) Sonar Noise Measuring Set 
during this report period. However, work on this project will begin 
again shortly.

delivered. 

B. Field Support Services 

During this report period, ARL:UT provided the following field support 
services: 

1. returned a repaired plotter (HP 9872A) to MOTU 5, San Diego, CA; 

2. provided NAVSHIPYD PHILA with a sensor calibration and readout 
monitor while its units were being repaired; 

3. repaired and returned a sensor calibration and readout monitor 
to NAVSHIPYD PHILA; 

4. provided NAVSHIPYD PHILA with a spare SCR control PCB 8A8 to 
repair a defective power supply;
