Hardware- in -Loop Computer Simulation Technology for Field Tests of Capacitance Fuzes

Introduces a method of modeling based on test data , applying the nonlinear least square method for system resolution and estalishes a mathematical model for the proximity target characteristics of capacitance fuzes , as well as a system of hardware-in-loop computer simulation. The system can be used to simulate the field test processes of capacitance fuzes facing different conditions of intercourse between the target and the projetile , under the control and management of the computer . It permits to give out the burst height and an analysis of the operation of the fuzes , as well as to investigate the effects of interference signals , background signals etc ., on the fuze . The system can also stand alone as a unit , independent from the control of a computer , and can also be used in field tests of fuzes of other types .
