The signal processing department develops new methods, algorithms, programs and computational architectures for signal processing in intensive pulse jamming presence having various origin, which is being used in radars, radio-navigation, mobile and fixed communications.
The surveyed algorithms are studied in general-purpose Personal Computers though numerical analysis or mathematical modeling by Monte Carlo statistical analysis.
The research encompasses following scientific areas:
The department consists of six researchers: one professor – Doctor of Science, three Associate Professors and one Research Associate. Three of them have been awarded a PhD degree in the last five years.
- multi-sensor detection and estimation of signals reflected by targets in radar or communication networks in the presence of intensive probability pulse jamming;
- Space Time Adaptive Processing (STAP) of radar and radio-navigation signals in intensive probability pulse jamming presence;
- stepped-frequency processing for Ground Penetrating Radars and following algorithm implementations on reconfigurable hardware – Field Programmable Gate Array (FPGA) processors.
- radar or communication signal detectors keeping constant false alarm probability (CFAR processors) in the presence of pulse jamming having Poisson or binominal probability of appearance and Rayleigh amplitude distribution;
- moving target joint detection and trajectory estimation through the Hough transform in a single sensor or a sensor net. The explored radar or communication signals have Rayleigh probability distribution and are applied in an intensive pulse jamming environment with various probability of distribution;
- flying target coordinates estimation in radar or communication network aiming a survey of non-conventional methods: the trilateral, described by Caspers, or the monopulse interference, described by Chen.
The scientific results are published in honored international and national journals and conferences. The total publication number of the department in the last five years are totally 81; chapters in scientific books published abroad 2; international journals 10; international conferences 39; national journals 23; national conferences 7.
The research staff has intensive contribution in project preparation and project management. More than 12 IIT projects to the value of 40 thousand BGL are developed in the last five years. The project participation includes Bulgarian Ministry of Education and Science, Bulgarian Ministry of Defense; Institute of Information Technologies (IIT); MPS Ltd.
