Some differences between gated CW and pulse radars in RCS and imaging measurements

The author discusses some of the significant differences between gated CW (continuous wave) and pulse instrumentation radars for making RCS (radar cross section) and imaging measurements. General similarities and differences are discussed under the heading of fundamental operating characteristics. Specific performances of the two types of systems are discussed, including system sensitivity, gate performance, clutter rejection, and measurement times. Other considerations such as Doppler and interpulse modulation are also discussed
