A coded pulse radar proximity fuze with improved electronic countermeasure protection, comprising a transmitting means for radiating a recurring sequence of three pulses of two alternate frequencies at a target, each of said pulses being separated in time by the desired radar round trip delay time and each of said sequences of pulses being separated in time by a greater time than the desired radar round trip delay time b means for receiving reflections of said recurring sequence of three pulses radiated at a target by said transmitting means c means connected to said receiving means and to said transmitting means for combining the output of said receiving means with a portion of the output of said transmitting means d means connected to said combining means for amplifying that portion of the output of said combining means having a frequency equal to the difference between said two alternate frequencies and e means connected to said means for amplifying for detecting a sequence of two pulses separated in time by the desired radar round trip delay time.
