Abstract In a pulse radar apparatus target returns are detected, sampled, digitised per range quant and frequency analysed. The apparatus comprises a cell classification unit (5) for deriving from the spectrum of the target returns a cell classification signal, whose logical values indicate that the target returns within a radar cell are classified, in the first instance, to be from a moving target and from a fixed target. In a microprocessor (15) the cells, which collectively cover one single target, are combined to form a cluster, while a signal representative of the target covered by the cluster is determined. Furthermore in the microprocessor (15) a cluster classification signal is derived, whose logical values indicate that the target returns within the cluster are classified to be from a moving target and from a fixed target. The signal representative of the target covered by the cluster is read out if it is derived from target returns classified to be from moving targets.
