The thesis aims to explore how artificial intelligence can be applied to identify various targets based on their micro-Doppler signatures in passive radar systems, with the potential to improve target classification accuracy.

Background

In modern electronic surveillance, the ability to accurately identify targets is crucial. Micro-Doppler signatures, which capture the unique movement patterns of objects, offer a promising method for distinguishing between different targets, such as drones, vehicles, and personnel. However, extracting meaningful information from these complex signals remains a significant challenge, especially in passive radar systems. The need for efficient and reliable target identification has driven the development of innovative approaches that leverage artificial intelligence to automatically and accurately classify targets. The use of micro-Doppler signatures is emerging as a promising solution, significantly enhancing the efficiency and reliability of passive radar systems.

Thesis Description

The thesis aims to develop and implement AI-driven algorithms for target identification in passive radar systems by analyzing micro-Doppler signatures. This involves several key objectives:

• Data Collection: Gather simulated and real-world micro-Doppler signatures from various target types under different conditions.
• Model Development: Design and train machine learning models tailored to recognize and differentiate between the subtle variations in micro-Doppler signatures.
• Performance Evaluation: Assess the accuracy, efficiency, and robustness of the developed models in real-world scenarios.

The ultimate goal is to create a reliable AI-based target identification system for passive radar that provide a strategic advantage in surveillance and defense applications.
