We present in the paper results of a generalised micro-Doppler analysis that is suited to high range resolution radar. The target echo energy is here represented in the three dimensional space of time, Doppler, and additionally range, what can provide more information on target micro-motion than the standard micro-Doppler analysis which is performed in the time-Doppler plane. The analyzed signals were recorded with a Ka-band FMCW radar of a high 1GHz bandwidth, which could provide good resolution in range, time and velocity. Here, we present a new method to visualize jointly micro-range and micro-doppler effects of a running man observed on the background of ground interferences.

Magnetocardiography is an advanced technique of measuring weak magnetic fields generated during heart functioning for diagnostics of huge number of different cardiovascular diseases. In this paper, k-nearest neighbor algorithm is applied for binary classification of myocardium current density distribution maps (CDDM). CDDMs from patients with negative T-peak, male and female patients with microvessels (diffuse) abnormalities and sportsmen are compared with normal subjects. Number of neighbors selection for k-NN classifier was performed to obtain highest classification characteristics. Specificity, accuracy, precision and sensitivity of classification as functions of number of neighbors in k-NN are obtained. Depending on group of heart state, accuracy in a range of 80-88%, 70-95% sensitivity, 78-95% specificity and 77-93% precision were achieved. Obtained results are acceptable for further patient's state evaluation.

In this paper, the potential of an avionic polarimetric weather radar is shown. The simulator used for such a purpose is a statistical simulator capable of reproducing complex signals as those gathered by an onboard radar, along with polarimetric and Doppler observables. The simulator, developed in the framework of the CleanSky European program, can be an useful tool to evaluate the radar prototypes that in a near future will be mounted on real aircrafts to enhance pilots' environmental awareness, which is declared as a major CleanSky objective.

MIMO approach to implementation of radar tomography is described and preliminary results of its experimental validation using Ka-band noise waveform ground based SAR are presented. MIMO concept with time-division to of Tx/Rx channels is applied to emulate 2D aperture synthesis combined with range resolution due to wideband random signals. Two linear synthetic apertures have been used for transmit and receive antennas oriented in vertical and horizontal directions, respectively. Range resolution in radar tomography is determined by power spectrum width of the transmitted signal, while its cross-range resolution is defined by 2D aperture dimensions. This enabled generation of 3D coherent radar images in radar tomography mode.

One of the key issues of security is fast and accurate analyses of different threats in above ground and underground structures of different applications. Among the most dangerous threats, that may end with fatal and destructive results are fires and explosions. Modern threat identification systems must be quick-acting and reliable. The development of contemporary detection devices is oriented to the creation of integrated systems ensuring monitoring of all possible threats as well as respective measures for threat prevention. A comprehensive security system enables identification of emergency and pre-emergency conditions and have WiFi modes of operation. This paper describes results of experimental investigations to identify and process information signals from different sources. The described works are necessary for designing the device integrated module of identification which is based on the constant monitoring on potential threat that may take place in manufacturing sites and tunnels. The potential threats discussed in the paper are: · Explosion, which is based on the monitoring of overpressure and methane concentration control in the media; · Fire, which identification is based on the monitoring of flame and smoke parameters. Besides the reliable identification and generation of the emergency signal, the proposed multifunctional device will ensure also the activation of the protective systems to reduce the damage and fatal consequences after explosion and/or fires.

In this contribution, several classifiers are employed to study patient-specific epileptic seizure prediction quality using intracranial electroencephalogram signal (iEEG) for dogs and humans suffering from epilepsy. New approach to extraction of correlation-based features in sliding time window within the EEG epoch is proposed. Classification performance was evaluated by area under receiver operating characteristic curve (AUC). Influence of duration of time window on results of classification was studied. For epileptic seizure prediction in humans, best classification is showed by support vector machine classifier for time window Tw= 60 sec. (AUC=0.9349); for seizure prediction in dogs, highest obtained AUC is 0.9432 for SVM classifier and Tw= 30 sec.

In this paper the distributed software environment called Conan dedicated to numerical computing is presented. The environment provides mechanisms for running separate units of execution and communication between them. It is written in C++ and can work both on Linux and Windows systems. Thanks to its versatility, Conan can be used to build complex distributed computing systems. It was created for radar signal processing, however, it can be used in other applications as well.
