Özet Sinyal kaynaklarının konumlarının bulunması, hedefleme, rota tayini gibi askeri sistemler başta olmak üzere doğal yaşamın incelenmesi, maden rezervlerinin tespiti gibi sivil uygulamalarda da etkin bir şekilde kullanılmaktadır.2.Dünya savaşıyla birlikte önemi keşfedilen yön bulma konusu, kaydedilen gelişmelerle beraber günümüzde önemli bir kullanım alanına sahip olmuştur. Tek bir kaynağın yerini belirlenmesi ile başlayan çalışmalar günümüzde, alt uzay tekniklerinin geliştirilmesiyle birlikte aynı anda birden fazla sinyalin konumunu tespit edebilir hale gelmiştir....
Ultra wide band (UWB) antennas are of huge demand and Vivaldi antennas as well as the TEM Horn antennas are good candidates for UWB applications as they both have relatively simple geometry and high gain over a wide bandwidth. The aim of this study was to design such an antenna that achieves the maximum antenna gain over a bandwidth between 1 GHz to 10 GHz while minimizing the size of the antenna...
This paper describes the design, analysis and measured performance of PIN diode Single-Pole Double-Throw (SPDT) Switch and its feeding circuit. The SPDT switch is done for the prototype implementation of The Security Purpose Pulse Doppler Radar which is intended to be used for security applications. Shunt-Shunt Switch topology which includes two cascaded quarter-wavelength sections that each one is...
Low cost multiple input multiple output (MIMO) Wireless Data Acquisition System (WDAS) for long range operation has been developed, simulated and implemented. The reference input and output measurement circuits for various sensors to measure strain, vibration and temperature have been designed, and integrated. Low cost microcontroller is used to process and condition the signals that are acquired...
