Článekpeer-reviewedpublished version Omezený přístup Statistical Analysis of Ground Clutter from FM Based Passive Radar(Springer, 2019) Bhatta, Abhishek; Pidanič, Jan; Mishra, AmitStatistical characterization of ground clutter information for radar systems is a topic that requires a detailed understanding. In this work, we characterize the ground clutter information from data captured by two Frequency Modulation (FM) based passive radar systems placed at different locations in the Czech Republic. Since the target models are statistically defined by the Swerling models, each of which is based on a particular distribution, we attempted to connect the ground clutter with some of the known distributions. The analysis is performed in three steps. The empirical distribution is fitted with some of the well-known distributions. Two different goodness-of-fit tests (named chi-squared test and Kolmogorov-Smirnov test) are performed on the obtained data by comparing the empirical distribution with the fitted distributions to determine which distribution is the best fit. The observations are analyzed and the results are considered in detail.Konferenční objektpeer-reviewedpostprint Otevřený přístup The Wind Farm Simulator of Reflected Signals in Primary Radar System(University of Indonesia, 2017) Pidanič, Jan; Juryca, Karel; Suhartanto, HeruThe spreading of the renewable energy especially wind farms, increases possibilities of negative influence on the detection capabilities of primary radar systems. The paper deals with modelling of a simulator for reflected signals from wind farms. The developed simulator enables echo simulation from wind farms, with many variable input parameters, that helps with analysis of influence. The simulator simplifies and speeds up the development of wind farm mitigation techniques, on primary radar systems. The paper describes characterization of the model of the simulator that includes multipath reflection and a brief analysisKonferenční objektpeer-reviewedpostprint Otevřený přístup The Modelling of Wind Turbine Influcence in the Primary Radar Systems(University of Indonesia, 2017) Pidanič, Jan; Juryca, Karel; Suhartanto, HeruWind turbines or wind farms present a major source of renewable energy. The expansion of wind turbines across the world rapidly increases. Unfortunately, for radar systems, wind turbines are a big source of clutter that can negatively influence the behavior of the detection capabilities of radar systems, or even totally “blind” radar systems. The problematic of mitigation of the influence of the wind turbines on radar systems is highly variable and depends on parameters of the wind turbines and radar systems. The main negative parameters of wind turbines are large Radar Cross Sections and Doppler shift spread of reflected signals. For the determination of general mitigation techniques, it is important to make a deep analysis of the different types of scenarios using a developed simulator of reflected signals from a wind turbine. This paper describes developed simulator and wind turbine parameter analysis
