Technology Development Process

Technologies in Tellumat

• DSP Processing from IF (Sub Nyquist Sampling)• Simulation with “Hardware-in-the-Loop”• Selected elements of SDR (Software Defined Radio)• UML for software design / documentation• SysML for system engineering• RTOS Real Time Operating System (VXWorks)• Software designed to international certification

requirements (RTCA DO-178B, 278 etc)• Combination of proprietary and OEM (Open

Standard) hardware

Technologies in Tellumat

• 3-D modelling of mechanical elements• Thermal analysis / cooling design using finite

element analysis• Electronically steerable antenna arrays• Micro-strip / micro-wave design using simulation

tools (ADS - Advanced Design System)• High powered solid state pulsed amplifiers• Monopulse processing / tracking• Cryptographic software and hardware

Primary Radar Activities
