he paper introduces a real-time high-speed acquisition, and storage system of radar video echoes, which uses the high-speed parallel single-chip Transputer T425 as the central CPU and combines it with the high-speed A/D (35MHz, shit), D/A (50MHz, shit)and FIFO. Compared with the present acquisition and storage system of radar video echoes,this system solves the problems for good acquistion result and real time recognition of radar target video echoes. In the meantime, D/A circuit is devised to combine the manual recognition with the automatic recognition so as to enhance the recognition rate of the facility. It is proved practically that the system has the following feattlres: (1) high sampling rate and great storage capacity; (2) fulfiling the data transmission and communication between processors by use of the standard Transputer chains; (3 ) programming with parallel Occam language, so that the system can not only exert the parallel function, hilt also carry out the data acquisition and processing synchronously, which is very important in real-time signal acquisition and processing systems.
