THE WAY OF SIMULATION TEST AND STUDY OF ITS APPLICATION FOR SFM SYSTEM DURING OPENING PERIOD

In this paper, a way of simulation test for obtaining multi-object's velocity using Doppler radar is proposed according to the kinematic characteristics of Sensor-Fuzed Munitions (SFM) manifested in the opening process which is devided into subprocesses of suspension lines tightening, opening inflation and stabilized deceleration. The actual simulation test of SFM system for the opening process is completed successfully. Using the equations of each of the subprocesses of the opening process, an application analysis of test results is conducted from which the characteristic parameters needed for ballistic calculation are showed. It is shown that the real motion characteristics of SFM system in the opening process can be obtained by this way. The results satisfy completely the basic needs of centroid motion calculation of relerant ballistic phase. The way is practical and reliable for applications.
