Abstract : The patent describes a microwave sensitivity control (STC) circuit for use with a radar receiver. The STC control element is included as a part of a microwave mixer. The receiver is operated with STC not applied until the target return is sufficiently large to cause the transfer function of the mixer-IF preamplifier to just begin compressing. At this time control bias is applied to the STC diodes which reduces the electric field intensity at the plane of the mixer diode by 25 db as the target returns become larger.
