There is a reason the matlab example plots a spectrogram and doesn't take an FFT and that is because the FFT of the chirp isn't really a generally useful thing to do. The chirp signal itself tests a system over a range of frequencies without having to leave the time domain, the point (in my mind) is to eliminate the need for taking an FFT ... fmcw雷达框图. 调频连续波雷达如要由收发器和带微处理器的控制单元组成，收发器如果使用单个天线进行同时发射和接收，fmcw雷达需要铁氧体环形器来分离发射和接收信号，对隔离度要求较高。当然，若使用收发分离的贴片天线，成本会相对低一点。 Jun 19, 2008 · Offering radar-related software for the analysis and design of radar waveform and signal processing, Radar Signal Analysis and Processing Using MATLAB® provides a comprehensive source of theoretical and practical information on radar signals, signal analysis, and radar signal processing with companion MATLAB® code.

Figure 2. Examples of a) FMCW denial jamming and b) FMCW deceptive jamming. Denial Jamming. An arbitrary FMCW type strong jamming signal that falls into the receiver bandwidth raises the noise floor of the victim radar. This denial jamming may cause small targets (that is, small radar cross section (RCS)) to disappear due to the poor SNR.

Frequency Modulated Continuous Wave (FMCW) Radar . It is also possible to use a CW radar system to measure range instead of range rate by frequency modulation, the systematic variation of the transmitted frequency. What this does in effect is to put a unique "time stamp" on the transmitted wave at every instant.
