Abstract :
Modern experimental radar systems that are used for advanced research into persistent surveillance and topics such as high range resolution need an ultra wide bandwidth of several hundred megahertz. There is furthermore a requirement for a high Spurious Free Dynamic Range (SFDR). This presents a unique challenge to the designer of the receiver- and exciter system. This paper presents the design challenges and one solution to these challenges.
