Mölndal, Sweden


Improved air combat awareness with aesa and next generation signal processing
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)


The challenge
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”
