Description
Master Thesis, 30 hp: Hard Real-Time Performance and High-Precision Timestamping in Software-Defined Radar Architectures
Are you a student eager to apply your theoretical knowledge and fresh perspectives to real-world challenges? At Saab, we believe that innovation thrives on new ideas, and your master thesis project could be the spark that ignites our next technological breakthrough.
Your role
We recognize the immense value that students bring to our company. Your academic rigor, combined with your enthusiasm for cutting-edge technology, allows you to approach problems with a unique and insightful lens. At Saab, you'll have the opportunity to collaborate with experienced engineers and specialists, gaining invaluable practical experience while making a tangible contribution to our growth and development.
Background
Modern radar systems increasingly use software-defined architectures to improve flexibility and introduce new signal-processing functionality faster. At the same time, radar applications require deterministic timing, low latency, bounded jitter and precise timestamping of data and external events.
This thesis will evaluate a high-end, CPU-based, Linux server and compare it with a traditional FPGA-based solution. The aim is to identify the limits, trade-offs and practical applicability of CPU-based timing in software-defined radar systems.
Description of the Thesis Project
As a thesis student, you will study how scheduling, interrupts, cache effects, power management, memory contention, drivers and workload interference affect timing. You will configure and evaluate real-time Linux mechanisms such as PREEMPT_RT, CPU isolation, real-time priorities and interrupt affinity.
You will develop measurements for latency, jitter, deadline misses and timestamp precision under controlled and stressed conditions. You will compare CPU-based hardware timestamping, PTP and IEEE 1588 mechanisms with FPGA-based event capture and data processing, then translate the results into architectural recommendations.
Expected outcome
- A measurement-based assessment of hard real-time performance on the target system.
- An evaluation of timestamp precision and robustness under realistic system load.
- A comparison of CPU and FPGA approaches across determinism, accuracy, flexibility, complexity and integration effort.
- Recommendations for which radar timing functions suit CPU-based implementation and which should remain in FPGA hardware.
Your profile
The project is suitable for 2 students with an interest in real-time systems, Linux, embedded systems, computer architecture, networking or FPGA technology
You are in the final stage of Computer Science, Computer Engineering, Electrical Engineering, Engineering Physics programme or equivalent and are about to begin a 30 hp thesis project.
Experience with C/C++, Linux system programming, performance measurement or hardware interfaces is beneficial.
We provide the support and guidance you need to translate your theoretical knowledge into practical solutions. Join us and become a driving force behind Saab's technological advancements!
This position requires that you pass a security vetting based on the current regulations around/of security protection. For positions requiring security clearance additional obligations on citizenship may apply.
