Abstract

The conventional filtering methods are difficult to meet the
demand of ground radar detection performance. Then pulse Doppler technique in
high-altitude target detection has shown good performance of clutter suppression.
The demand of the clutter suppression ability needed to detect target in a low
altitude is illuminated by theoretically analyzing and simulating. And confirms
the need of the PD technology to ground-based radar when detecting in low altitude.
The inherent problems are discussed which are caused by the application of PD
technique to the ground radars and the corresponding solutions are also presented.
Research indicates the feasibility of appending the PD technique and the clutter
can be suppressed by this method effectively.
