A practical approach for RF system design of an S-band modern digital radar receiver

RF system simulation constitutes a practical tool in radar receivers design. In fact, a particular type of simulation called “budget” is very useful in RF system design of modern digital radar receive systems. Starting with low noise amplifier (LNA) and ending with analog to digital converter (ADC), these systems can be presented in a synthetic format. A typical modern radar receiver is first presented and described stage by stage. Subsequently, some design considerations are discussed. Finally, simulation results are presented and commented.
