About the feasibility to realize a nonlinear radar with processing at the probing signal frequency

The conditions for the implementation of a nonlinear radar using probing signal having form as periodic sequence pairs radio pulses with different amplitudes and equal energies, are considered. energies reflected compared in locator receiver each pair, which makes it possible to detect reflections from devices at frequency by violating equality these energies. A numerical experiment was performed evaluate dependence current through germanium silicon diodes their amplitude parameters acting sinusoidal voltage variable amplitude. As result, found that nonlinearity can be detected before diode is completely "opened" if two on differ other least one half times. Since pulse proportional powers, durations unchanged, should non-linearity determination ratio between cross-sections non-linear objects amplitudes. To obtain quantitative estimates, simulation incidence flat, linearly polarized wave half-wavelength dipole folded loaded performed. It model type significantly affect both values degree influence values, so detection requires higher power levels than theory predicts.
