Method for measuring the effective scattering surface of objects in express mode in a natural background with radar means and a device for its implementation

摘要

1. The method of measuring the effective scattering surface of objects by radar means, which consists in determining the difference in the power of the reflected signals from the measured object and the reference reflector or graded pulses of the standard signal generator, introduced into the measuring circuit of the energy coupler, recorded by receiving devices with attenuators calibrated in a logarithmic scale in the studied wave range, characterized in that in express mode and in a natural background environment, a certain they show comparative values of the reflective characteristics of the standard, objects, and artificially created targets by standard navigation, surveillance, shooting, and other radars; they alternately attenuate signals from these targets by an attenuator built into cascades of intermediate frequency amplification circuits that are not subjected to temporal gain control and calibrated to a logarithmic scale to threshold level, register it visually on the screen of the used radar station and determine the difference in signal levels on the scales at tensors corresponding to EPR in m.2. A device for determining the reflective characteristics of objects in the radar wavelength range, which consists of a measuring radar, attenuator, standard signal generator, calculator, recorder, reference reflectors and targets under investigation, characterized in that the path of the intermediate frequency amplifier is not subjected to a temporary adjustment of sensitivity, standard for example, a ship radar integrates an attenuator with a scale to ensure a smooth decrease in the value of the reference signal
