... coinciding with the radar initial wave propagation direction. In other words, a frequency dependence is defined by the RCRO extension along the initial wave propagation direction. It follows ... scatter radar tends to be pulsed and forward scatter continuous wave (CW). Forward scatter radar shows an increase in sensitivity 540 Wave Propagation For the interference law (40) unde...

... and zero total power flux. A standing wave is formed in the waveguide. This wave results from the interference of the forward and backward waves with wave numbers h having equal absolute values ... and “strong” interactions between the travelling wave in the waveguide and the modulation wave are studied. Propagation of electromagnetic waves in the medium whose permittivity and...
