Başlık: Bio-inspired Observability Tools for Active Sensing and Sensor Selection
Özet: Flying insects have an unexpectedly remarkable sensing capacity. For instance, Drosophila, the fruit fly, can track chemical plumes by estimating the ambient direction without directly measuring it. In this talk, I will introduce the observability tools we developed to better understand the active sensing decisions made by insects and the importance of sensor selections. Specifically, I will address how to determine system observability levels (i.e., estimator performance limits) in the presence of process and/or measurement noise, and for particular state variables, e.g., state of charge or state of health of a battery. I will conclude the talk with potential engineering applications.

Başlık: Cognitive Electronic Warfare (CEW)
Özet: Electronic Warfare (EW) involves the use of the electromagnetic spectrum to gain a tactical advantage over opponents. It has two main components: Electronic Support (ES), which improves situational awareness by detecting, intercepting, identifying, and locating signals, and Electronic Attack (EA), which disrupts enemy radars through jamming and deception. Traditional ES methods, which rely on static emitter libraries and deterministic signal processing, along with classical EA techniques based on pre-programmed jamming strategies, were effective against earlier and predictable threats. However, modern operational environments present challenges such as the rapid emergence of adaptive radar systems, low-probability-of-intercept (LPI) waveforms, dense multi-emitter scenarios, which undermine the static nature of conventional EW approaches. This has led to the development of cognitive techniques that introduce adaptability and intelligence into electronic warfare. Cognitive Electronic Support Measures (CESM) utilize machine learning, adaptive signal processing, and real-time decision-making to identify emissions and dynamically adjust sensing strategies. Similarly, cognitive electronic attack (CEA) extends traditional EA by employing adaptive and autonomous jamming or deception techniques to deny detection and tracking by modern radars. This presentation introduces the fundamental concepts of electronic warfare and cognitive electronic warfare, highlighting the motivations for incorporating cognition into modern EW systems and radar technologies, with a particular emphasis on the applications of Cognitive Electronic Support Measures (CESM).

Başlık: From Graded Composites to Smart Materials: Adaptive Surfaces for Soft Robotics
Özet: A materials-driven approach for achieving adaptive behavior in soft systems is presented, beginning with the mechanical design of graded and layered polymer nanocomposites. By systematically tuning layer architecture, concentration gradients, and coating thickness, smooth stress distribution, enhanced strength–toughness balance, and force-dependent stiffness are obtained. These results highlight that mechanical response emerges primarily from structural design rather than chemistry alone, establishing a framework for mechanically adaptive composite surfaces. Building on this foundation, an emerging direction toward smart material functionalities—specifically magnetic field–induced modulation and piezoelectric self-sensing—is outlined as a potential route for adaptive interfaces in soft robotics.

Başlık: Improving MRI with RF Engineering
Özet: Magnetic resonance imaging is a medical imaging technique that provides anatomical images with excellent soft-tissue contrast. MR scanners use strong static magnetic fields, magnetic field gradients and radio frequency (RF) fields to create images. Today, the demand for ultra-high-field MR systems is constantly increasing due to their SNR and contrast advantages. New engineering solutions are needed to improve patient safety and imaging performance at these field strengths. This talk will consist of three parts. The first part will summarize our efforts to demonstrate the safety of MRI at 10.5 T, which made it possible to obtain the world's first human brain images at this field strength. The second part will focus on the development of new RF antenna arrays and RF safety validation methods for UHF MRI applications. The last part will present new strategies for safe imaging of patients with metallic implants.

Başlık: Neuromorphic computing - what, why and how
Özet: Since its first use more than 35 years ago, the term "neuromorphic" in the context of computation has carried different meanings to scientists and engineers. The continuous advancement in the field appears to be accelerating in both pace and scope over time, fueled by real-time and low-energy AI thrust. This impetus compels cross-disciplinary R&D collaborations across neuroscience and engineering disciplines more than ever. After reviewing the historical context, we will explore how the growth in neuromorphic computing has significant and exciting implications. We will subsequently examine neuromorphic computing approaches, with emphasis on electronic implementations, supported by examples from our research in resource-constrained systems.

Başlık: Current Research Activities in the Department of Communications and Information Technologies, ASELSAN
Özet: In this talk, ongoing research activities conducted within the Department of Communications and Information Technologies are presented. First, a bistatic OFDM-based integrated sensing and communication (ISAC) system is examined under a single-target scenario, considering both line-of-sight (LOS) availability and blockage cases. A sliding-window sensing receiver architecture is proposed, through which the inter-symbol-interference (ISI)-free sensing range is extended beyond the cyclic prefix (CP) duration by exploiting pilot symbols embedded in the time–frequency grid. The performance of the proposed architecture is evaluated in terms of range and velocity estimation accuracy and is benchmarked against the Cramér–Rao bounds (CRBs) for the bistatic ISAC setting.
In the second part, a jamming-resilient PUCCH receiver is proposed, in which decoding reliability is assessed through a threshold-based mechanism designed to bound the probability of decoding errors. Furthermore, a channel-estimation-error-aware equalizer tailored for DFT-s-OFDM waveforms is introduced to yield more accurate log-likelihood ratio (LLR) computations. Simulation results demonstrate that decoding reliability can be effectively evaluated without reliance on CRC, even under jamming conditions, thereby improving the robustness of 5G control signaling in contested environments.
