The wide application of artificial intelligence technology in the military field has led to the continuous evolution of war forms. To meet the challenge of intelligent warfare， this paper analyzes the development trend and the role of artificial intelligence technology and discusses the necessity of developing artificial intelligence defense technology in the military. From the view of "hard strike" and “soft strike”， the technical ideas of defense against anti-AI weapon systems and AI security defense architecture are given. The technical principles of pollution strike， reverse strike， backdoor strike， and confrontation strike are analyzed emphatically. Suggestions for strengthening AI defense technology research are given from six aspects： top-level design， application review， data governance， primary analysis， command art， and human-machine hybrid intelligence.

In this paper， the steady-state current-carrying capacity and impact current-carrying capacity of the flexible PCB cable inside a micro aircraft are calculated and designed theoretically. By the MIL-STD-275 standard and empirical formula， the steady-state current-carrying capacity of the flexible PCB cable is reviewed and calculated. With reference to GJB 4057-2000， the impact current-carrying capacity of the flexible PCB cable is estimated. For the theoretical calculation and estimation， the steady-state current-carrying test under the condition of twice the theoretical value and the pulse current test under the condition of 10 times the theoretical value are designed. The test results are consistent with the expected ones， which verifies the correctness of the theoretical calculation. In the current-carrying capacity test， the temperature of the flexible PCB under the current-carrying state of each current value is obtained， and the thermal simulation is carried out by Flotherm software for verification. The stable temperature of the flexible PCB under each current value state is simulated. The thermal simulation results conform to the actual test results， which verifies the authenticity and rationality of the experimental data. The results of the current-carrying capacity experiment and simulation data in this paper can provide experimental data support for the design of PCB in micro aircraft for subsequent short-time operation.

The electrical connection of each device inside the ultra-micro aerial vehicle（UMAV）， mainly relies on the traditional way of lead wire welding. There are many problems in this way， such as low efficiency， error-prone， easy to broken welding wire， difficult debugging， etc. Ordinary wire-type cables and connectors are easy to use， but too bulky to suit the UMAV. A design method of fuzz button flexible electrical connection component for UMAV is proposed. The fuzz button component is used as the connector， the rigid-flexible joint plate is used as the transmission cable， and the three-dimensional design of aircraft structure is combined to realize the reliable electrical connection of various electrical devices inside the UMAV.

For the anti-jamming problem of global positioning system（GPS） receiver in high dynamic environment， We studies the received signal model of equidistant linear array and the basic principle based on covariance matrix expansion， and simulates and analyzes the effect of two classical anti-jamming algorithms based on covariance matrix expansion： Mailloux algorithm and Zatman algorithm in high dynamic environment. Through Matlab simulation， the results show that compared with the conventional method， Mailloux method and Zatman method can effectively widen the null formed from the interference direction when the array element is an equidistant linear array， which can improve the anti-jamming effect in high dynamic environment and enable the receiver to capture satellite signal.
