    Developed and tested algorithms (and software) for generation of 3-D acoustic images with an enhanced performance. The achieved improvement of the angular resolution of a random microphone array is up to circa 2.7 times (at near field zone). The opportunity to localize noise sources with the fractional bandwidth equal to 2 was shown with a multi-site microphone array.

    Supported a monitoring of acoustic emission of rolling ball bearings, at industrial companies. Gained in-depth experience with random transducer arrays.

    Participated in several projects dedicated to a generation of images and to a measurement of displacements using active and passive mono- and multi-site noise radars, namely:
    - provided simulations for a graceful degradation in phased antenna arrays,
    - provided a system performance calculation and data for Kalman filter, and
    - took part in a signal processing for generation of 3-D images using MIMO Ground Based Noise Waveform Radars with the time-division of signals in transmission/reception channels (Matlab, post-processing).
