Abstract

PURPOSE:To set a reception gate position while evading a reception limitation period before transmission and a clutter priod by perventing transmitted pulses and a target reflecting signal from overlapping with each other by using transmission repetition frequency pulses (high PRF) which differ in period. CONSTITUTION:High PRFs which differ in period are selected so that the transmitted pulses and target reflected signal overlapping with each other, and the position of a high PRF receiving gate corresponding to the position of high PRF conversion distance of the actual distance of a target is put in a target receivable range between a clutter range and the reception limitation period before transmission. Then, comple mentary distance information on corresponding distance synchronized with the high PRFs are calculated by arithmetic processors 12 and 16 on the basis of the information on the high PRF conversion distance and the obtained complementary distance informa tion, i.e. PRF pulses which is minimum in time from pulse reception time to next transmitted pulse time and has the shortest repetitive period are selected by compara tive decision circuits 17 and 18 according to the information on the high PRF conver sion distance. Then, the distance information corresponding to the PRF pulses selected from the information on the high PRF conversion distance is selected by a selecting circuit 25 to set a receiving gate position on the basis of the selected distance informa tion.

考慮しておく必要がある。Here, a reception restriction period is set just before and after the transmission of the transmission pulse in order to prevent the reception pulse and the transmission pulse from overlapping. Then, when performing angular tracking of a target, distance information (high P RF conversion distance information) based on several transmission pulses with a high transmission repetition frequency is obtained, and a transmission pulse of a predetermined P RF is selected from among them. A reception restriction period is also set for the selected transmission pulse. Therefore, when obtaining high PRF conversion distance information, it is necessary to take into consideration the reception restriction period, especially the reception restriction period at the leading edge of transmission.
