Laser-guided weapons have been widely used in combat,and their precision characteristics are outstanding for striking important military targets such as bridges.Each type of bridge has different load transfer methods and different weak points.A typical bridge is selected for stress analysis,and a targeting point for laser-guided weapons is selected based on curve fitting.Combining the aircraft assault angle,the indicator safety indicating range and “shooting” tactics,an application method of air-to-ground laser-guided weapons against the bridge is proposed.This study can not only serve as a theoretical reference for air-to-ground attack bridge operations,but also provide a theoretical basis for the allocation of air defense forces to important targets of river-sea bridge.

How to effectively evaluate the effectiveness of anti-ship missile weapon system under the condition of confrontation is an important measure to improve the combat effectiveness of anti-ship missile weapon.Based on ADC model,the factors is comprehensively analyzed,characteristics and effectiveness indexes that affect the anti-ship missile combat capability system,and establishes the evaluation index system.Analytic hierarchy process (AHP) is used to determine the weight vector of each sub-index,and the fuzzy comprehensive evaluation is used to calculate the capability value of each sub-index.The capability value of each index is calculated by using the index method to establish combat effectiveness evaluation model of anti-ship missile weapon system.The sensitivity of different indicators is analyzed to the whole anti-ship missile weapon system,to provide reference for the future development and use of anti-ship missile.

In digital array radar (DAR), channel mismatch has a serious impact on many indicators such as low sidelobe beamforming, signal to interference ratio of output signal and anti-interference. To correct the error, the channel equalization technique is gradually applied to the array error correction and has been rapidly developed. The current channel equalization techniques are divided into time domain least square fitting method, frequency domain least square fitting method and Fourier transform method according to the equalizer weight coefficient solving method. The main principles and difficulties of each method are analyzed emphatically, and the advantages and disadvantages of various methods are compared. The difficulties of the digital array radar channel equalization technique in future development are summarized.
