A method for determining the moment of issuing a command to launch a protective munition, initially combined with a radar station and a protected object and fired at a given moment at an estimated point in space for a meeting within a known time after a shot with a target approaching the radar, at which the moment of issue commands to launch a protective munition are set at the beginning of the occurrence and detection of a signal on the radar with a frequency of Fdo = 2Vofо / С, when the target will be located at a distance from the radar equal to Do + (Vi / Vo) Do, where fо is the average frequency radiated radar of a continuous signal with frequency modulation according to a one-sided sawtooth linearly increasing law (NLFM signal), Hz, C - speed of light, m / s, Vo - radial speed of a protective munition, m / s, Vi - radial speed of a target, m / s, Do is the known distance from the radar to the intended meeting point of the protective munition with the target, m, characterized in that the radiated NLFM signal is artificially delayed for a known time and a difference signal is detected on the radar with a frequency equal to Fp = Fdo + Fo = 2Vofo / C + Fo.2 . A radar station (radar) for determining the moment of issuing a command to launch a protective munition containing a receiving and transmitting antenna, the output of which is working for reception, is connected to the first input of the mixer, the second input of which is connected to a low-power output of a continuous signal transmitter with frequency modulation on a one-sided ramp ramp law, and the output, through the filter of difference frequencies, to the input of the detector of signals of a narrow-band frequency spectrum, characterized in that the input of the transmit-receive antenna works yuschy to transfer, via the delay element,
