In this paper we consider the resource management task in closely spaced multiposition radar systems. The aim of the work is to develop an investigate approaches of avoiding resource overuse and mutual interference of the radars. We consider two levels of resource management: reallocation of active radars depending on the operational situation in area of responsibility the system to minimize used radar resources, and reallocation of frequency resources between active radars to avoid mutual interference. Fast suboptimal algorithms are proposed for both levels of optimization.

This paper presents strategies of the target localization in passive bistatic radar in the presence of multiple receivers and non cooperative illuminators. One of the algorithms based on ellipsoid intersections is analyzed. The individual target position is calculated from the bistatic range (BR) measurements using closed form equation based on the time difference of arrival (TDOA) algorithm. Aim of the algorithm is to find the intersection of ellipsoids in 3D space, which is a challenging task. The main performance issues, complexity of calculation and limitation are presented. A method of complexity and a memory requirement reduction using the direction of arrival is proposed and analyzed. The paper also deals with parallel implementation of Spherical Intersections algorithm using Graphics Processing Unit (GPU).

The new approaches for a single source direction-of-arrival estimation in a far-field and near-field cases are proposed. The main idea is estimation of the real spatial frequency directly along the uniform linear array by the single-shot data. The algorithm based on the autoregressive moving average model of the sinewave is applied for the frequency estimation. The precision of proposed methods is analyzed via computer simulations.

The design of the software radar signal generator using LabVIEW environment and the universal hardware NI PXI - 5673 has been presented in the paper. The stream up to four pulses with linear frequency modulation (LFM) and different durations and gaps between them can be generated in RF band up to 6.6 GHz. Other generation mode i.e. single, repeated and continual can be triggered manually or automatically. The configuration of the LFM pulses is carried out manually using software front panel.

The generation of synthetic environments, especially surface clutters, is of utmost importance for the study, the development and the qualification of radars. We focus here on sea clutter observed from airborne radars. The modeling of sea clutter is fairly different with regard to the ground clutter one. Indeed, the sea surface is a “deformable” surface unlike the land surface that is a “static” surface. Three levels of complexity of the clutter simulation are considered from the non-coherent single channel clutter up to coherent signals on multiple channels involved in complex detection modes such as STAP taking benefit on Space and Time correlations. A discussion on the interest of such STAP modes face to sea clutter ends the paper.

The NATO SET-225 Research Group has mainly been working to share experience of processing noise radar signals to address the limitations of current approaches in order to increase the range of noise radar applications. This paper defines a software defined L-band noise radar technology (NRT) demonstrator. This radar design process has originally started as an endeavour to build a digital signal processing (SP) back-end for noise radar SP studies and ended up as an L-band noise radar by itself. The SP back-end of the defined L-Band noise radar will be used with the X-band NRT demonstrator being designed by the NATO SET-225 group, during the trials to be performed at the Fraunhofer FHR Institute/Wachtberg in summer 2016.

In this paper, the E-pulse (extinction pulse) method known as aspect-independent ultra-wideband radar target discrimination technique is discussed. An alternative synthesis algorithm for the subsection polynomial E-pulse is introduced. The algorithm consists in building a skeleton E-pulse, its further extending and series of integration which all could be performed over the coefficients of basic functions. Not only the proposed algorithm performs up to a thousand times faster than direct matrix solution but it obtains the polynomial coefficients of the E-pulse sections avoiding the solution of a linear problem associated with ill-conditioned sparse matrix. It is proven that E-pulse signals synthesized by means of the fast algorithm and the direct one are exactly the same. To exposure the features of the E-pulse technique, two targets discriminating scheme has been simulated.

In this paper the possibility to distinguish hydrometeors with similar polarization properties inside the reflecting volume and estimating their differential impact onto polarization properties of reflected signal is made. The results are important for different practical applications of radar meteorology including drop size distribution estimate, rainfall intensity estimate, wind speed measurement, turbulence and strong wind shear detection.

New scientific findings always have historical roots, which are important to know for radar researchers. Different ideas and view points from the radar building beginnings are helping us to get the all picture of our research subjects, when we are trying to develop new radar systems on modern, up-to-date technology. Whereas Hungarian radar manufacturing had a relatively small impact on the radar technology compared to larger countries, their experts and scientists have achieved nevertheless significant results all over the World. It draws the attention to their small radar community. This paper is a brief summary of the facts are became public late after WWII.
