III. NONLINEAR RADAR This derivation fails for a nonlinear scatterer. To illustrate why, let us assume that the nonlinearity of the scatterer is small enough to admit a power-law expansion, a situation that illustrates our argument and is also simple mathematically (although other types of nonlinearities associated with clipping,Aug 15, 2022 · A simultaneous-frequency nonlinear radar is presented for detecting radio frequency electronic targets of interest. The radar transmits 20 frequencies (“tones”) between 890 and 966 MHz, at ... Dec 9, 2021 · In harmonic radar applications, images produced using algorithms of conventional radar applications experience some defocusing effects of the electronic targets’ impulse responses. This is typically explained by the dispersive transfer functions of the targets. In addition, it was experimentally observed that objects with a linear transfer behavior do not contribute to the received signal of ...
