FPGA based UWB radar system design

At the begining of project we aimed to design a radar which has different structure from other radar types. After some observation we decided to design an ultra wide band radar. First of all, transmitting circuit is designed. During this design it was very important to get very narrow pulse signal. The reason of getting narrow pulse is to broaden the frequency band. Then, receiver circuit was designed. We wanted to calculate the distance of movement from the radar because of that also a delay circuit was designed. The aim of delay circuit is to receive just signals from objects which are in movement. After we received echo signal with knowledge of delay time, we could know the distance. To confirm our design, first we used a simple microcontroller. Then, we used FPGA IC to get more reliable and minimized design.
