AN EXPERIMENTAL TWIN PULSE MTI S-BAND RADAR WITH PULSE COMPRESSION.
Abstract
The report describes an experimental twin-pulse MTI S-band radar capable of operating with or without pulse compression facilities. The major effect investigated was the contamination problem which exists when the pulse spacing is less than the extent of the clutter. Without pulse compression the effect is serious and pulse compression is shown to improve matters, enabling tracking of aircraft to take place through considerably extended clutter regions. For MTI operation one needs to limit hard and only retain the phase information, but when pulse compression is introduced between the limiter and MTI canceller, it is shown that losses of weak aircraft targets occur if they are present within one uncompressed pulse-length of a strong clutter return. Hence in these conditions the range resolution expected from the pulse compression is not obtained, the uses of the pulse compression being restricted to contamination-reduction and rain-clutter reduction.
