ABSTRACT:
A method and arrangement for generating a clutter threshold by means of a CFAR circuit. In the process the partial registers of the CFAR are subdivided into storage blocks each containing a plurality of cell, and a block sum is formed from the sample values stored in each storage block. To form the clutter threshold for a signal under test, the individual block sums are compared in pairs according to a predetermined scheme, during which the greater block sum is determined. From these resulting greater sums, the smallest block sum (minimum) is selected and, from this, the clutter threshold is determined with a predetermined weighing. According to an alternative method, the block sums are sorted according to an order of precedence. Thereafter, block sum having a predetermined ordered rank is selected from the sorted block sums, and the clutter threshold is determined from this selected sum after a predetermined weighing.
