【Abstract】 The function of each element of the integrator and the effect on its performance are dis- cussed by analyzing the working process of the integrator. The selection of parameters and setting up methods of the key elements in the integrator are denoted. The integrator is used for the acquisition system of backwaves from the earth radar. The integrator is set up in the laboratory and it is operated with good performance.更多还原
