Dynamic measurements of the effective scattering cross sections of targets

The true aspect of a target relative to the directivity of a radar is determined, and a method is proposed for ensuring a large dynamic range of signal amplitude measurements in dynamic investigations of scattering characteristics. To make this range possible, the signal is fed into the amplifier through an attenuator; it is controlled by the coefficient of attenuation of the attenuator in a way that is proportional to the low-frequency component of the process modulating the signal. This scheme of amplification is considered effective because the dynamic range of the signal is largely determined by its low-frequency component.
