A fusion system for constructing fused tracks for a plurality of targets from radar detections, comprising: a plurality of Ground Moving Target Indicator (GMTI) radars (R 1, R 2,..., and R n) configured for detecting said plurality of targets in an area of interest, each GMTI radar configured and operable for (i) scanning the area of interest within a corresponding scanning time frame, the scanning time frame of operation of each GMTI radar having a start scan time of scanning said area of interest and an end scan time of scanning said area of interest, and (ii) providing GMTI plots in the form of plot vectors including at least location data of said plurality of targets in polar coordinates; a plurality of conversion units (C 1, C 2,..., and C n) arranged downstream of said plurality of GMTI radars (R 1, R 2,..., and R n), each conversion unit being in data communication with a corresponding GMTI radar, and configured to receive the GMTI plots from the corresponding GMTI radar and to convert coordinates of each GMTI plot from polar coordinates to Cartesian coordinates, thereby providing converted plots; a plurality of GMTI trackers (TR 1, TR 2,..., and TR n) arranged downstream of said plurality of GMTI radars (R 1, R 2,..., and R n), each GMTI tracker being in data communication with a corresponding GMTI radar, and configured to create preliminary GMTI tracks of said plurality of targets from the GMTI plots provided by said corresponding GMTI radar; the fusion system characterized by: a fused plots generator arranged downstream of the plurality of GMTI trackers (TR 1, TR 2,..., and TR n) in data communication therewith, said fused plots generator configured for constructing fused plots by using said converted plots and said preliminary GMTI tracks; and a fused track generator configured to generate fused tracks for said plurality of targets from said fused plots. a plurality of Ground Moving Target Indicator (GMTI) radars (R 1, R 2,..., and R n) configured for detecting said plurality of targets in an area of interest, each GMTI radar configured and operable for (i) scanning the area of interest within a corresponding scanning time frame, the scanning time frame of operation of each GMTI radar having a start scan time of scanning said area of interest and an end scan time of scanning said area of interest, and (ii) providing GMTI plots in the form of plot vectors including at least location data of said plurality of targets in polar coordinates; (i) scanning the area of interest within a corresponding scanning time frame, the scanning time frame of operation of each GMTI radar having a start scan time of scanning said area of interest and an end scan time of scanning said area of interest, and (ii) providing GMTI plots in the form of plot vectors including at least location data of said plurality of targets in polar coordinates; a plurality of conversion units (C 1, C 2,..., and C n) arranged downstream of said plurality of GMTI radars (R 1, R 2,..., and R n), each conversion unit being in data communication with a corresponding GMTI radar, and configured to receive the GMTI plots from the corresponding GMTI radar and to convert coordinates of each GMTI plot from polar coordinates to Cartesian coordinates, thereby providing converted plots; a plurality of GMTI trackers (TR 1, TR 2,..., and TR n) arranged downstream of said plurality of GMTI radars (R 1, R 2,..., and R n), each GMTI tracker being in data communication with a corresponding GMTI radar, and configured to create preliminary GMTI tracks of said plurality of targets from the GMTI plots provided by said corresponding GMTI radar; the fusion system characterized by: a fused plots generator arranged downstream of the plurality of GMTI trackers (TR 1, TR 2,..., and TR n) in data communication therewith, said fused plots generator configured for constructing fused plots by using said converted plots and said preliminary GMTI tracks; and a fused track generator configured to generate fused tracks for said plurality of targets from said fused plots. a fused plots generator arranged downstream of the plurality of GMTI trackers (TR 1, TR 2,..., and TR n) in data communication therewith, said fused plots generator configured for constructing fused plots by using said converted plots and said preliminary GMTI tracks; and a fused track generator configured to generate fused tracks for said plurality of targets from said fused plots.
