MEASURING MODERN FREQUENCY CHIRP RADARS.

The article discusses the variety of short-frame and long-frame measurements that are available to cover modern chirp radar systems with bandwidths up to 20 gigahertz. It states that the primary measurements needed for a chirp is the linearity of the frequency change, and the measurements can include spectrum analysis, spurious signal detection, pulse timing, frequency and phase variations, chirp linearity, and digital modulation accuracy. Moreover, the selection of test equipment is driven by the extremes of the parameters of the signals that are being measured, and the test instruments are keeping up with the measurement needs of radar designers including specialty tests that are available for advanced chirp radar.
