Abstract: analog TV goniometer Angle deviation signal is generated by the goniometer detector conditions necessary for the performance test, based on the analysis of the working principle of the goniometer, on the basis of using the FPGA technology to TV goniometer Angle deviation signal simulation, after finished the hardware design, the design of the FPGA module inside, and carries on the simulation, the results show that this system can accurately simulate the Angle deviation signal of the goniometer.

Abstract: Owing to the increase in the types of battle field targets and the improvement of their velocity, flexibility and protection ability etc., the anti-air missile warhead with multiple explosive forged projectiles goes upon the stage. The warhead is based on multiple explosive forged projectiles with an alternate angled and layered structure. Thanks to its distributed explosive way and measures of safety barrier and anti-interference, all energy of this warhead can be controlled to release intensively in the dynamic damage volume, and damage the air target seriously even at a long distance. So it is used to attack the armor-protected targets in the air, and slso accomplish the task of distributing antimissile and antiaircraf ammunition etc.

Abstract: Aiming at the problem of existing time-frequency analysis methods was not effective to goniometer keeping fault of a certain missile, combined time -frequency analysis method of CWT and DWT for the fault was put forward based on the fault characteristic. The process of the method proposed was given and the time-frequency method of continuous and discrete wavelet transform was analysed. The signal when goniometer keeping fault occurred was analysed by the method that was put forward. The simulation showed that the method which was effective to the fault detecting could accurately detect the time and location of goniometer fault occurred.
