UHF RFID system has been mainly used in logistics,production and supply chain management. The implementation of UHF RFID reader with excellent performance is still challenging. This paper presents a UHF RFID reader implementation for EPC C1G2 protocol. EPC C1G2 physical layer architecture and some critical modules like encoder ,decoder, modulator and demodulator are described in details. All modules are verified in FPGA and the experiments demonstrate that the designed RFID reader baseband system could perform well.

Security is the main direction of ammunition for future development. Depending on the security level that ammunition relative to its life process may suffer major environmental stimuli factors, raising ammunition’s safety criterion, introducing safety parameters, establishing a theoretical model of ammunition safety performance evaluation. In the model, based on the value of the safety of ammunition, we divides the security level of ammunition. Based on this evaluation model to calculate the conventional bomb safety performance of the changing Mk-82’s insensitivity. We analyzed the influence of unexploded ordnance (UXO) on the overall safety performance of ammunition from the failure of the design. The results show that the end of unexploded failure design can significantly improve the safety level of ammunition. This model better reflects the inherent safety performance of ammunition, can provide theoretical guidance for the safety design of ammunition and safety performance evaluation.

The millimeter-wave terminal guidance ammunition monitoring scanning field is small. The modified design is in order to improve the search section trajectory guidance. This study established seeker search area to capture the target model, which leads to the missile engine unpowered glide distance formula after flameout. At the millimeter-wave terminal on the missiles contraction section ballistic. Each missile is designed for the flat road, the swash decline ballistic programs. Flat missile road program scans and does not shrink. Its flight speed falls and declines rapidly, has different gliding distance and terminal velocity. After the missile engine is flameout, its start-gliding speed is great. Ramp fell ballistic program enhances the air-air (or air-ground) guided missile’s gliding ability, helping to improve range. But shortcomings are that target tracking scanning domain contracts. Using the seeker optical axis in the pitch direction can achieve accurate positioning with the height precession. Two ballistic designs can both meet the target seeker’s scanning, thus effectively improve the striking precision.

The study of ammunition system of weapon with extra-high firing rate projectile screen is the new trend of precision strikes and shooting. In this paper the developments achieved in the field are described. Our study status of this task is presented. The key advanced techniques for the ammunition of this weapon system have been analyzed. It will play an important guiding role in the development of new concept equipment.
