NSA/WSACR/C1 - Instrument problem

A strong return artifact is present around 16 km.
  
This problem occurs when the number of range gates exceeds the number of gates that can 
fit within the pulse repetition time. Since the receiver is always sampling data from next 
pulse repetition period is sampled.
