Webtarget drops into the ‘Rayleigh region’. A rule of thumb: below resonance, target echo goes as the sixth power of the height. Cut the height in two and the echo drops by 64 (18 dB). This could result in a decrease in detectable range to 80km if it was originally seen at 200km.

WebPROBLEM. In Section 2.2.5 of the text, it was demonstrated that the radar cross section (RCS) of a target modeled as a set of “many” individual point scatterers was a sufficiently complex function of aspect angle (or frequency) that it could be modeled as a random variable; and further that the law of large numbers suggests that one assume an … WebThe Rayleigh region.
