Advanced High-Speed Signal Processing for Enhanced Air Combat Situational Awareness

This paper discusses an innovative High-Speed Signal Processing (HSSP) system developed by Ericsson Microwave Systems and Halmstad University. The project aims to integrate next-generation signal processing capabilities into compact, robust hardware suitable for AESA radar systems. Key features include improved beam jamming rejection, enhanced detection range, and effective ground mapping for slow-moving targets. The HSSP system achieves a performance of 1 TFLOPS within the constraints of current systems, addressing challenges in size, power, and robustness for modern airborne radar applications.

  2. Improved air combat awareness- with AESA and next-generation signal processing Main beam jamming rejection Active and Passive Search Communication Wide transmit beam Increased detection range Side lobe jamming rejection Ground mapping and measurements of slow ground moving targets (SAR/GMTI) Rejection of clutter and jamming (STAP)

  3. The challenge • The AESA performance should fit in the same“box” as today’s systems, considering • Physical size • Power dissipation • Physical robustness • The High Speed Signal Processing(HSSP) project • A joint project between Ericsson Microwave Systemsand Halmstad University, Sweden • The goal of HSSP: “1 TFLOPS in a shoe box”
