Abstract : This invention relates to range detection by power measurement and more particularly the detection of range by power measurement and the utilization of such detection for control of proximity fuzes in ground to ground missile applications. A proximity fuze is essentially a miniature radar transmitter-receiver used in missiles, artillery, shells, bombs, and rockets which trips the firing mechanism when the armed device approaches within a predetermined range of a target. However, in the presence of heavy jamming or in the case of failure of other fuzing methods, it is desirable to measure received power to determine when to explode the missile. In accordance with the present invention, a signal is emitted from the transmitter of the fuze, and the reflected signal is picked up by the fuze receiver. The reflected signal is sent to first and second filters which have predetermined characteristics. An automatic gain control (AGC) circuit in combination with aforesaid fuze receiver divides the output of the first filter by the output of the second filter.
