Measurement of Nonlinear RCS of Electronic Targets for Nonlinear Detection [PDF]
Journal of Electromagnetic Engineering and Science, 2022 The conventional radar technology is based on linear detection—i.e., the same transmit and receive frequencies are used. However, with linear radars, difficulties arise when detecting electronic objects with relatively small radar cross section (RCS). To
