Down-range test zone characterization for compact ranges

Radar cross section measurement in a compact range is often performed using real-time pulse techniques (gating). This allows unwanted reflected signals (not originating from the object under test) to be suppressed and thus enhances the accuracy of the measurement process. In such a setup, the target positioning within the target zone defined by the pulse process is critical, since it may lead to the distortion of actual target response if not performed properly. In this paper a technique is described that allows the down-range characteristics of the target zone to be measured. Measured results are presented.
