Fast coherent integration for migrating targets with velocity ambiguity

In wideband radar, fast moving targets migrate through range gate during the coherent processing interval. To preserve coherent integration gain, range gate walk has to be taken into account. In this paper, we propose a fast algorithm based on a Keystone-like transform that allows one to perform suc...

Description
Summary:In wideband radar, fast moving targets migrate through range gate during the coherent processing interval. To preserve coherent integration gain, range gate walk has to be taken into account. In this paper, we propose a fast algorithm based on a Keystone-like transform that allows one to perform such an integration in case of velocity ambiguous radar.
