File name 5990-5392EN Simulation and Verification of Pulse Doppler Radar Systems - Application Note c20141029

Keysight Technologies Simulation and Veriication of Pulse Doppler Radar Systems Application Note Introduction Modern radar systems that operate in environments with strong clutter, noise and jamming require advanced digital signal processing techniques. Direct analysis techniques often fail when designing such complex systems. Although simulation is often used, most simulation tools do not have enough models and integration capability to handle modern radar systems. This application note proposes a solution to this dilemma, a system-design methodology that uses SystemVue. Examples will be used to illustrate how advanced Pulse Doppler (PD) surveillance radar with moving target detection (MTD) and a constant false alarm rate (CFAR) processor can be designed by using a platform in the SystemVue tool. To ensure the design works properly, the platform can be connected to instrumentation for system test and veriication. This allows users to reduce their system development time and cost, while also decreasing their chances of unexpected system failures late in the system development process. 1.0 System Design Challenges Advanced radar systems are very complex, necessitating sophisticated signal processing algo- rithms. Effective algorithm creation requires both a platform for simulation and for veriication. Models for signal generation, transmission, antennas, T/R switching, clutter, noise, jamming, receiving, signal processing, and measurements are also needed to create advanced algorithms. Most simulation tools do not have enough models and the integration capability needed to design such complex algorithms. SystemVue provides an effective and eficient environment for algorithm creation. 03 | Keysight | Simulation and Veriication of Pulse Doppler Radar Systems - Application Note 2.0 Signal Processing Algorithm Creation The system-design methodology proposed below uses SystemVue.
