| The possibility of using parametric scatterers for long distance marked object detection is studied. For this purpose,
amplitude and phase characteristics of parametric scatterers need to be accounted for and the receiver sensitivity
is to be increased by coherent accumulation. Techniques to compensate the sync signal sequence in coherent accumulation
of response signals are considered. |
