Range Bin--- area of resolution in distance used in the IBIS-S system.
Radial displacement ---displacement of the range bin or the pixel along the direction joining the Range bin or pixel to the IBIS system i.e.along the Line of Sight.
Thermal SNR ---ratio between the power of the received signal in the single Range bin or pixel and the power of the thermal noise of the sensor.Normally expressed in dB.
Estimated SNR--- ratio between the power of the received signal in the single Range bin or pixel and the estimate of the power of disturbing phenomena (including thermal noise) which impacts on that
Range bin or pixel.Normally expressed in dB.This value is
computed as the ratio between the mean value and the variance of
the amplitude of the signal of the measurement point.
Phasor--- complex number represented on a polar graph which reproduces the signal received from the single Range bin or pixel.
Clutter---any type of undesired electromagnetic signal that is however detected by the sensor and disturbs the measurement.
