The block diagram of ultrashort pulse system of a near radar-location developed in article on the base of a single-crystal radar chip. It has advantages in comparison with pulse systems. It is shown that use of single-crystal transceivers allows to reduce energy con-sumption of the transceiver, to reduce dimensions of system and to improve spatial resolution in comparison with pulse radars. The algorithm of reception of an input signal of ultrashort pulse system of a near radar-location on the basis of synchronous accumu-lation of a large number of received pulses and restoration of a form of the received signal is developed. According to an algorithm the cycle on number of the received pulses should be organized. Each received pulse divides by time for several samplers, each of which corresponds to the average level of a signal on an interval of sampling. For realization of accumulation of pulses the array of counters in which values of account of excesses of discrete values of a signal of thresholds is formed. The index of each value of the counter corresponds to number of the sampler. In a cycle on number of the received pulses there is a creation of the array of counters of excesses of discrete values of a signal of threshold value. Results of restoration of ultrashort pulse signal from his mix with a harmonious hindrance are given when amplitude of a hindrance is 4 times more than signal amplitude on a receiver-s input. Realization of the developed algorithm of reception of ultrashort pulse signal allows to reach the signal-to-jamming ratio at the level of 6,9 dB when using of 1000 accumulated pulses (thresholds).
