Master Thesis, 30 HP: Investigating AI-Based Signal Detection in Raw IQ Data for ESM Systems

The thesis aims to explore the potential of detecting radar signals directly from raw IQ data for Electronic Support Measures (ESM) systems, bypassing or reducing the need for traditional preprocessing steps. The ultimate goal is to enhance both real-time response and detection accuracy by leveraging AI techniques. This research could lead to more efficient signal detection mechanisms in complex and high-noise environments.

Background

In modern electronic warfare, ESM systems play a crucial role in detecting and classifying radar signals from a variety of sources. Traditional ESM systems often rely on extensive preprocessing of incoming IQ data, which can introduce latency and reduce overall system efficiency. As adversaries develop increasingly sophisticated radar technologies, the need to enhance signal detection capabilities has become more urgent to maintain a strategic advantage. This has driven the demand for innovative approaches that leverage artificial intelligence to streamline signal processing, thereby enhancing both the speed and accuracy of ESM systems. With advancements in AI and machine learning, there is now an opportunity to explore whether AI models can detect and classify signals directly from raw data, which can potentially reduce latency, and improve the accuracy of the system, which is vital in defense applications where response time is critical.

Thesis Description

The aim of this thesis is to develop and evaluate AI-based algorithms capable of detecting radar signals directly from raw IQ data within ESM systems. The project will involve:

• Investigating existing AI techniques for signal detection.
• Designing and implementing a model tailored to interpret raw IQ data without extensive preprocessing.
• Training these models on diverse datasets to recognize various radar signatures.
• Evaluating the model’s performance in terms of detection speed and accuracy in comparison to traditional methods.
• Exploring how well the model generalizes across different signal types and noise levels.

This thesis offers the opportunity to contribute to cutting-edge technology in electronic warfare and defense systems.
