A two-stage detector is proposed to accommodate high computational load requirements of modern radar systems. The first stage of the proposed system is a low-complexity detector that operates at an unusually high false alarm probability value around 1/10. This stage is to prescreen and eliminate some of the test cells with relatively few operations. The second stage operates only on the cells passing the prescreening stage and implements a high-complexity detector at a desired system false alarm rate. Due to the detector cascade, the second stage has a large amount of computational load reduction, on the order of 10 folds, in comparison with the single-stage systems. The mathematical analysis of the described two-stage detector is presented, and the relations for the false alarm and detection probability are derived. The numerical results show that it is possible to achieve a significant computational load reduction at a negligible performance loss with the proper selection of detector parameters.

Multi target tracking with acoustic power measurements using emitted power density Orguner, Umut (null; 2010-07-29) This paper presents a method to achieve multi target tracking using acoustic power measurements obtained from an acoustic sensor network. We first present a novel concept called emitted power density (EPD) which is an aggregate information state that holds the emitted power distribution of all targets in the scene over the target state space. It is possible to find prediction and measurement update formulas for an EPD which is conceptually similar to a probability hypothesis density (PHD). We propose a Gaus...
An Adaptive Hybrid Beamforming Scheme for Time-Varying Wideband Massive MIMO Channels Kurt, Anıl; Güvensen, Gökhan Muzaffer (2020-06-01) © 2020 IEEE.In this paper, adaptive hybrid beamforming methods are proposed for millimeter-wave range massive MIMO systems considering single carrier wideband transmission in uplink data mode. A statistical analog beamformer is adaptively constructed in slow-time, while the channel is time-varying and erroneously estimated. Proposed recursive filtering approach is shown to bring a remarkable robustness against estimation errors. Then, analytical modifications are applied on an analog beamformer design metho...
A software for simulation and controller development for high frequency high voltage power supplies Ertan, Hulusi Bülent; Demirel, O (2000-08-18) This paper describes a software developed for the simulation of high voltage (up to 125 kV), high frequency power supply for radiology equipment. The main components of the power supply are an AC-DC conversion stage, a high frequency inverter feeding a resonant load. The resonant load is the impedance reflected to the inverter side of the, high voltage high frequency transformer Seeding the X-ray tube. The software has modules for each of the components of the converter mentioned above, which can be modifie...
Slow moving target detection for airborne radar systems by dynamic programming on SAR images Gurer, Gorkem; Koc, Sencer; Candan, Çağatay; Orguner, Umut (2019-04-01) A dynamic programming based approach is proposed to detect slow moving, low reflectivity targets for airborne radar systems. The suggested method utilizes the reflectivity amplitudes of the SAR image, possibly containing multiple slow moving targets, and poses the target detection problem as a maximum likelihood sequence detection problem. Dynamic programming is applied to capture the target related features such as along track smeared target signatures in the SAR image to this aim. Typical clutter and targ...
An energy efficient hierarchical approach using multimedia and scalar sensors for emergency services Kızılkaya, Burak; Ever, Enver; Sustainable Environment and Energy Systems (2019-7) Recently, environment monitoring and detection systems became more accessible with the help of IoT applications. Furthermore, connecting smart devices makes monitoring applications more accurate and reliable. On the other hand, optimizing the energy requirement of smart sensors especially while transmitting data has always been very important, and there are different applications to create energy efficient IoT systems. Detailed analysis of lifetimes of various types of sensors (survival analysis) has theref...
