Özet:

The scope of this thesis is to implement radar emitter emulator in a low cost, portablehardware for operational and educational purposes. The model enables pulse train generation in real environment belonging to radar emitters for military exercises. The motivation comes from another research area which is to design effective algorithms for deinterleaving mixed pulse sequences in a suitable hardware and this thesis, covers the work done for implementing a hardware that generates mixed pulse sequences. First of all, a basic radar emitter model is built up using laboratory instruments by considering basic radar emitter models. Technical specs of these instruments have to be known well to find out how many emitters can be emulated simultaneously and what the limits of these emulations are. After giving emulation results, trigging signal generator externally to obtain complex mixed pulse sequences is mentioned. In the following section related schematics are given about implementing radar emitters. Cost efficient way of emitter emulation is mentioned by using wideband RF synthesizer/VCO with integrated RF mixers and some microwave components in the following section. A board is designed including all required components to implement radar emitter emulation. Tests are implemented in laboratory environment. Finally test results and technical specifications of the design are given. Also cost calculations of the implemented designs are done in the final section and some examples related to the use of emulators in environmental scenarios are given. Future work is also explained again in this final section.
