Design Aspects for Dual Polarized Phased Array Antennas with Low X-pol Contribution
Dennis Vollbracht, Selex-ES GmbH (Neuss, Germany)
Antenna engineers know about the challenge to design phased-array antennas with very low x-pol contribution for the beam steering range. This paper gives an overview about the design aspects of dual-polarized microstrip patch phased-array antennas with very low x-pol contribution. Starting from a single radiator design, two 32-element-arrays are investigated in x-pol contribution during phased-array operation with CST MWS and compact range measurements. In particular, the performance parameters for phase-taper-optimized and differentially-feed antenna arrays are highlighted. It will be shown, how the x-pol radiation will be generated and how the antenna radiation pattern can be used to identify the dominating source of x-pol contribution of antenna arrays.

Enhanced target detection and localization by cueing in multistatic passive-active radar systems
T. Brenner, L. Lamentowski, R. Mularzuk, PIT-RADWAR SA (Warsaw, Poland)

The Deployable Multiband Passive Active Radar (DMPAR) concept has been originally proposed by[1], [3], [4] and the SET-152 RTG in the Final Report of the group [6]. In this approach, a collocated system comprising of 4 passive and active components has been connected through the algorithms of centralized and decentralized fusion of signals or plots, respectively. Performed simulations gave promising results and through the course of work of SET-195 [2] these were confirmed by experimental data. The scenarios from trials on which we registered signals and data are described in [2,11]. The algorithms of signals and data fusion was developed on basis [8] and described in [9].

Innovative Algorithm for Wide Band Digital Signal Processing in modern AESA RADAR Architecture
Roberto Lalli, Caterina Rapisarda¸ Alessandro Manuale, Valerio Tocca, Land & Naval Defence Electronics Leonardo S.p.A. (Rome, Italy.)

RF sampling technology, already available in L,S and C bands, allows acquiring the whole operative RADAR bandwidth. In this context, to overcome digital processing bottlenecks,an innovative FPGA based algorithm, targeting wide band RADAR signal has been designed. The algorithm is able to digitally process wide band signals, with a FPGA operative clock frequency lower than the one requested by standard Nyquist-based processing. The same algorithm can also be used to reduce the FPGA operating clock frequency and therefore power consumption, a burning issue for small form factor modules.The algorithm is characterized in terms of functionalities, performance and FPGA implementation; an actual case study is presented.

Technology Trends for Future Radar
Hans van Bezouwen and Dr. Michael Brandfass, HENSOLDT (Ulm, Germany)

The continuously growing complexity of military and commercial scenarios requires a progressive development of novel radar technologies along with its sophisticated algorithms and mode operations. One of the strong trends in radar applications is the progression of signal digitization along with its processing capabilities towards the frontend for both the waveform generation in transmit as well as the echo discretization on receive. The radar antenna frontends are split-up in ever more sub-apertures, driving the increase of RF-channels to supply the radar processing chain and enabling advanced processing techniques. Examples are adaptive nulling of antenna directivities toward jammers, space time adaptive processing (STAP) to effectively suppress clutter and interferences while maintaining target detection sensitivities, as well as multiple beams on receive and generation of multiple transmit beams e.g. to enable simultaneous mode operations, enhance target tracking and increase target detection verification.

A Family of Secondary Surveillance Radars based on Conformal Antenna Array Geometries
Massimo Angelilli, Leopoldo Infante, Paolo Pacifici, Leonardo Company S.p.A., Land and Naval Defense Electronics Division (Rome, Italy)

A SSR (secondary surveillance radar)/IFF (identification friend or foe) Radar family based on a conformal phased-array antenna geometries is presented in this work. The systems don’t use rotating parts (i.e. rotary joint) increasing the reliability and reducing in service costs for site installation where the environmental condition are extreme (as for example in desert area or icy sites). A scalable antenna architecture and beamforming is presented, achieving interesting common designs of critical items. In a military application, the 360° conical shape of the antenna ground plane reduces the radar-cross-section and allows electronic scanning in spite of mechanical rotation and eliminates the scan-loss or coning typical of planar array geometries. A 128 radiating elements conformal array has been built and tested in an antenna test facility showing satisfactory agreement with the theoretical model.
