ABSTRACT:
An arrangement for protecting radars against unwanted echos such as "clutter" using an angular divergence measuring signal. This signal is compared with two predetermined thresholds + xo and - xo. When the probability of the two thresholds being exceeded by the divergence signal is greater than a predetermined value Po, the arrangement generates a logic signal which is used to prevent the tracking circuits of the radar from locking on to the received echo.
