1. 1. Airborne Radar Ground Clutter Suppression Using Multitaper Spectrum Estimation & Choosing DPSS Parameters

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Carl-Henrik Hanquist; [2018]
   Nyckelord :DPSS; Multitaper; Radar;

   Sammanfattning : One of the biggest challenges in any airborne radar is to distinguish a target from a strong ground echo. The main problem is that the ground echo, called ground clutter, can be up to a million times stronger than the response from the target in question. LÄS MER

3. 2. Design av stimuligenerator för radarmålsökare

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Johan Brodin; [2009]
   Nyckelord :målekogenerator; radarmålsökare; stimuligenerator;

   Sammanfattning : During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). LÄS MER

4. 3. Design of a channel board used in an electronic warfare target simulator

   Magister-uppsats, Institutionen för systemteknik

   Författare :Peter Andersson; [2006]
   Nyckelord :Saab Bofors Dynamics; Electronic Warfare Simulator; Target echo generation; Circuit board; DRFM; FPGA; Microcontroller; Ethernet;

   Sammanfattning : 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. LÄS MER
