The RADARs use complex techniques such as stagger PRI, jitter PRI with frequency agile characteristics. The frequency agile RADARs switch frequencies with in a pulse to get different types of advantages. Today lot of RADAR signal processing takes place on FPGA platform. These signal processing algorithms include pulse parameters estimation, deinterleaving of mixed pulse patterns, processing com...

The area of micro strip antennas has seen some inventive work in recent years and is currently one of the most dynamic fields of antenna theory. This designing is very easy and chip in micro strip antenna designing. In this paper SHF band frequencies x-band frequency 10 GHz and Kuband frequency 13GHz are gives the best result, the antenna has become a necessity for many applications in recent w...

For locating maritime vessels longer than 45 meters, such vessels are required to set up an Automatic Identification System (AIS) used by vessel traffic services. However, when a boat is shutting down its AIS, there are no means to detect it in open sea. In this paper, we use Electro-Optical (EO) imagers for noncooperative vessel detection when the AIS is not operational. As compared to radar s...

The paper deals with the Zagreb Terminal Airspace capacity. The basic scenario has been modelled using the RAMSPlus simulator and capacity has been calculated by using the WMSE method which takes into account the peakhour workload based on air traffic controllers’ tasks. The problem of traffic congestion has been analyzed and several case study scenarios have been simulated. The conducted simul...

The application of Ku-band VSAT Systems to single layer hexagonal micro strip patch antenna is thoroughly simulated in this paper. The radiating elements in this antenna are composed of two triangular and one rectangular slots from the conventional micro strip patch antenna. These slots are engraved in the rectangular and triangular patch, joined together in two structures, and by single probe ...

Software Product Line approach enables improved variability management by handling similar software products as a whole and expressing commonalities and variabilities implicitly which leads to high software reuse levels. This approach increases product quality, decreases costs and time-tomarket. In this work, firstly, problems encountered in software development efforts performed in scope of si...

The Centre for Australian Weather and Climate Research (CAWCR) is developing the Australian Community Climate and Earth System Simulator (ACCESS), a global, coupled atmosphere-ocean climate model based on the Unified Model of the U.K. Met. Office. A high-resolution atmosphere-only version combined with a 4DVAR assimilation system is being used for numerical weather prediction. Validation of the...

Radar scattered time domain response can be modeled by natural poles using singularity expansion method (SEM) in resonance region. In this paper, limitation of the conventional Extinction pulse (E-pulse) method is brought out and a hybrid of conventional Extinction pulse and auto-regressive (AR) method is proposed for robust discrimination of radar targets. A new target discrimination number (T...

This paper presents a systems view of the Autonomous Navigation and Sensing Experimental Research (ANSER) project. ANSER is one of the most advanced UAV projects of its kind, which is aimed at demonstrating Decentralised Data Fusion (DDF) and Simultaneous Localisation and Map (SLAM) building on multiple cooperative UAVs. The demonstration of DDF and SLAM require both navigation and terrain sens...
