Experiences
Signal Processing
- analysis of stationary and nonstationary signals, e.g. time-frequency-analysis
- digital signal processing in time and frequency domain, e.g. matched filtering,
correlation methods
System Design and Construction of Prototypes
- systems with high speed microprocessor architecture by using digital signalprocessors
(Motorola, TI) and microcontrollers (Zilog, Intel)
- using complex Field Programmable Gate Arrays (FPGA) for controlling apparatus, e.g.
digital controlling a transmitter array to swing the sound beam
- peripheral components for digital signal processors, e.g. analog to digital converters
Development of Analogue Hardware
- receiver with gain and frequency control
- phase shifter array for the two-dimensional beam swinging while receiving acoustical
waves
- high power puls transmitter with peak performance of 2 kW
Programming Technics
- high level languages (C/C++, Pascal) under DOS, Windows 3.11 and Windows95 / WindowsNT
- low level languages for microcontrollers (Zilog, Intel) and digital signalprocessors
(Motorola, Texas Instruments, Analog Devices)
Hydroacoustic
- methods of acoustical detection of sedimentary layers
- linear and nonlinear (parametric) acoustic
- possibilities and methods of beam forming and beam swinging
