Radar System Design and Interference Analysis Using SystemVue
应用文章
This application note outlines key features of the Keysight Technologies, Inc. SystemVue software for performing radar system design and jammer/interferer analysis. Some of the key areas to be discussed include how to implement a radar Chirp waveform, design an RF chain for the transmitter and receiver, and perform pulse-compression analysis using fast Fourier transform (FFT) based convolution. Finally, the radar system is tested in the presence of unwanted interference and jamming signals to study the impact of such unwanted impairments on radar performance.
1.1 LFM Chirp for Radar System Design
SystemVue offers a flexible platform to create custom signals. SystemVue floating-point Data Flow components were used to model the LFM Chirp source. The integrator on the left increments time until the value for the pulse period is achieved, causing it to reset and start over.
