A radar indication device, comprising: a receiver configured to receive, from two radar devices (1, 2), data relating to a target echo received by a radar antenna (11, 31) of one of the radar devices (1, 2), and data relating to a target echo received by a radar antenna (11, 31) of the other radar device (1, 2), respectively, wherein the radar devices (1, 2) have target detectable ranges that are partially overlapping; a determiner configured to determine whether the target echoes indicate the same target object; and a display unit configured to display target echoes, characterized in that: the device further comprises an ID applier configured to apply a global ID to target echoes detected from non-overlapping detectable ranges of the radar devices (1,2) and to apply a single global ID to target echoes when the determiner determines that the target echoes from the two radar devices (1, 2) indicate the same target object, wherein the global ID is an ID uniquely assigned for every target echo indicating a single target object, and different IDs are assigned to target echoes indicating different target objects; and the device is arranged such that, when the target echo detected by both radar devices (1, 2) is selected on the display of one of the radar devices, the selection of the target echo is informed to the other radar device. a receiver configured to receive, from two radar devices (1, 2), data relating to a target echo received by a radar antenna (11, 31) of one of the radar devices (1, 2), and data relating to a target echo received by a radar antenna (11, 31) of the other radar device (1, 2), respectively, wherein the radar devices (1, 2) have target detectable ranges that are partially overlapping; a determiner configured to determine whether the target echoes indicate the same target object; and a display unit configured to display target echoes, characterized in that: the device further comprises an ID applier configured to apply a global ID to target echoes detected from non-overlapping detectable ranges of the radar devices (1,2) and to apply a single global ID to target echoes when the determiner determines that the target echoes from the two radar devices (1, 2) indicate the same target object, wherein the global ID is an ID uniquely assigned for every target echo indicating a single target object, and different IDs are assigned to target echoes indicating different target objects; and the device is arranged such that, when the target echo detected by both radar devices (1, 2) is selected on the display of one of the radar devices, the selection of the target echo is informed to the other radar device. the device further comprises an ID applier configured to apply a global ID to target echoes detected from non-overlapping detectable ranges of the radar devices (1,2) and to apply a single global ID to target echoes when the determiner determines that the target echoes from the two radar devices (1, 2) indicate the same target object, wherein the global ID is an ID uniquely assigned for every target echo indicating a single target object, and different IDs are assigned to target echoes indicating different target objects; and the device is arranged such that, when the target echo detected by both radar devices (1, 2) is selected on the display of one of the radar devices, the selection of the target echo is informed to the other radar device.
