USED IN THE ANALYSIS OF SHIP TRIAL DATA TO STUDY THE ELASTIC RESPONSES 

 OF SURFACE SHIP STRUCTURES TO RANDOM SEA ENVIRONMENT. CALCULATES STA- 

 TISTICAL AND PEAK TO PEAK PARAMETERS ASSOCIATED WITH DIGITIZED RANDOM 

 DATA. PROCESSES UP TO lA- CHANNELS OF DATA CONCURRENTLY. AND ALLOWS 

 SELECTION OF EITHER CALIBRATED OR UNCALIBRATED RESULTS. REF. NSRDC

PARTIAL AND ORDINARY COHERENCE 



LANGUAGE - FORTRAN IV 



AND MAP 

 COMPUTER - IBM 7090 



PROGRAM PRTCOH CALCULATES THE PARTIAL COHERENCE FOR RANDOM DATA FROM A 

 LINEAR SYSTEM, AND OCOH CALCULATES THE ORDINARY COHERENCE FROM THE 

 SAME DATA. THE DATA IS ASSUMED TO BE STATIONARY RANDOM DATA FROM A 

 MULTIPLE-INPUT SYSTEM WITH A SINGLE OUTPUT. BOTH PROGRAMS COMPUTE THE 

 TRANSFER RESPONSE FUNCTION FOR EACH INPUT. REF. APPLIED MATHEMATICS

SAVED (SHOCK AND VIBRATIONAL EXPERIMENTAL DATA 

 REDUCTION) 



LANGUAGE 



COMPUTER 



FORTRAN IV 

 AND MAP 

 IBM 7090 



REDUCES BLAST TEST DATA FROM ANY ONE OF FOUR TYPES OF TRANSDUCERS — 

 VELOCITY METERS, ACCELEROMET ERS , PRESSURE GAUGES AND STRAIN GAUGES. 

 THROUGH PROGRAMMED OPTIONS THE INPUT DATA, AFTER BEING CALIBRATED, MAY 

 BE SMOOTHED, FILTERED OR LISTED BEFORE BEING PLOTTED AS A FUNCTION OF 

 TIME. FOR VELOCITY DATA, TRANSDUCER CORRECTIONS WERE APPLIED AND DIS- 

 PLACEMENT IS COMPUTED AND PLOTTED. FOR ACCELERATION DATA, VELOCITY 

 AND DISPLACEMENT ARE COMPUTED AND PLOTTED. INPUT DATA IS READ FROM A 

 DIGITAL MAGNETIC TAPE IN A PREDEFINED FORMAT. DESCRIPTION IS IN NSRDC
