Apparatus is provided for the automatic in-line measurement of background noise for MTI radar with automatic suppression of samples not originating from noise. The background noise level is determined by making use of summing and shifting operations only, and the suppression of samples not originating from noise is obtained by utilizing the information derived from a normal radar detector so that samples identified as true targets shall not contribute to the calculation of background noise level. The apparatus comprises a multiplexer circuit (22), a first shifting circuit (23), a storage element (24), a second shifting circuit (25), an inverter (21), and a counter (26).
