1. Waveform agility for robust radar detection and jamming mitigation
University essay from Uppsala universitet/Fasta tillståndets elektronikAbstract : In this report metrics for jamming resistance and radar performance of waveform sets are described and developed, and different sets of waveforms are optimized, evaluated and compared. It is shown that without additional processing or PRI jitter, waveform sets can reach jamming resistance a few dB worse than what is provided by PRI jitter alone, and together with PRI jitter a few dB better.

2. Design of a channel board used in an electronic warfare target simulator
University essay from Institutionen för systemteknikAbstract : A channel board was designed for a DRFM circuit. The DRFM is implemented in a Virtex-4 FPGA from Xilinx. In the future a similar channel board is intended to be used for target echo generation in ELSI which is an electronic warfare simulator at Saab Bofors Dynamics in Linköping. READ MORE

3. Implementation of a Digital Radio Frequency Memory in a Xilinx Virtex-4 FPGA
University essay from Institutionen för systemteknikAbstract : Digital Radio Frequency Memory (DRFM) is a technique widely used by the defense industry in, for example, electronic countermeasure equipment for generating false radar targets. The purpose of the DRFM technique is to use high-speed sampling to digitally store and recreate radio frequency and microwave signals. READ MORE
