ASORPS (Advanced Sonar Range Prediction
System) was developed by Professor Chen, Chi-Fang and her team.
ASORPS v3.0 can predict the sonar detected
performance by combining with ocean models, high-performance acoustic
calculation models and ocean environment databases. The prediction can be
shown on the Operating System Interface of GIS, Geographic Information System
in order to let the result visualized. Scientific visualization not only
increases the understanding of battlefield situation, but also can lower
the training costs of staffs.
ASORPS v3.0 is a useful system for ROC Navy to estimate the
anti-submarine forces. Through predicting the sonar detected performance,
one can accomplish “real-time” tactical deduction in different hydrology
latest version, ASORPS 3.0 Office Version, is now available.
Introduction of ASORPS V3.0
ASOPRS V3.0 is structured by a
modularization model, and is calculated by numerical simulations. The
calculated results can provide tactical needs for analysis and application
on antisubmarine operations.
The acoustics calculation model divides the high and low
frequency, and increases the calculated speed. In addition, ASOPRS v3.0 can
calculate the multi-azimuth and multiple operation questions.
The display module can mark the shadow zone and the
convergence zone, display the different azimuth figures, which include the
transmission loss, detection probability, and the ray trace. The result
will be exported to GIS. On the GIS’s interface, one can overlap different
layers, to provide tactical needs about anti-submarine and multi-fleet.

I. The preliminary
assessment of U.S Navy said that ASORPS v3.0 is very close to the U.S
system, IMAT (Interactive Multi-sensor Analysis Training).
II. ASORPS v3.0 can combine other
marine environmental database. Because it uses delicate grids, the
prediction for Taiwan’s peripheral environment is more accurate than

provide tactical needs for analysis and application on antisubmarine
IV. ASORPS v3.0 can enhance the detection capability
with the Taiwan peripheral environmental databases（especially at the west-south and east-north areas）, which included noise , reverberation, and substratum.
V. ASORPS v3.0 provides visualization
of result, which can simulate maneuvers of multi-fleet combining the
environment. This function can decrease the training costs of staffs.

Fields of Application
for ROC Navy has two main applications: real-time prediction on the sea,
and forecasting on the land.
Real-time prediction on the sea
I. Combining with
the environmental information of the local marine area. (The environmental
information include the local hydrology, geography and substratum.)
II. Calculating high-performance
acoustic model immediately.
III. Providing the sonar detected performance of
different sonar systems on fleets.
IV. Providing the tactical forecast instantly.
Forecast on the land
I. Forecasting sonar
detected performance of different sonar systems.
II. Displaying the tactical
distribution of the sonar detected performance on multi-platform.
III. The forecast information can be use on other
The optimized value from ASOPRS can provide to the
decision-maker for tactical planning.
