An Integrated Framework for Complex Radar System Design
- Magazine Article
Modern radar systems are complex and depend heavily on advanced signal processing algorithms to improve their detection performance. At the same time, the radio front-end must meet challenging specifications with a combination of available components, implementation technologies, regulatory constraints, requirements from the system, and signal processing. This application example shows how NI's Visual System Simulator™ (VSS) system simulation software enables radar system architects and RF component manufacturers to design, validate, and prototype a radar system.
The project in this example, Pulse_Doppler_Radar_System.emp, illustrates key models and simulation capabilities available for practical radar design. The project and resulting measurements highlight how to configure a pulse-Doppler (PD) radar and set up the simulation to obtain the metrics of interest for radar development. The entire PD radar system project includes a linear FM (LFM) chirp signal generator, RF transmitter, antennas, clutter, RF receiver, moving target detector (MTD), constant false alarm rate (CFAR) processor, and signal detector for simulation purposes.
