Characterizing Radar Components and Subassemblies
应用文章
As derived in Part 1 of this series, the radar range equation captures the essential variables that define the maximum distance at which a given radar system can detect objects of interest. Because those variables relate directly to the major sections of the system block diagram, they provide a powerful framework for the essential process of understanding, characterizing and verifying the actual performance of any radar system.
Parts 2 and 3 of the series defined the pulsed radar signal, described ways to measure the power in those signals, and presented readily available ways to measure the essential characteristics of pulsed signals: frequency, timing, power and spectrum. Part 4 examined the use of vector signal analysis (VSA) and wideband instruments—signal analyzers and oscilloscopes—to measure frequency, phase, and more, in today’s increasingly complex radar signals.
