Based on the actual process of dipping sonar in on-call submarine searching, combined with the classic extended spiral search method, a multi machine dipping sonar on-call submarine searching model was established. A submarine motion model was built based on the possible avoidance measures that submarines may take during the on-call submarine searching. We calculate the variation of detection probability of suspended sonar with response time and response distance of dipping sonar. Moreover, we also analyze the military force requirements of dipping sonar for submarine search under different response time and response distance of dipping sonar. So the obtained relevant conclusions can provide theoretical basis for tactical decision-making of anti-submarine helicopter response submarine search.
Aiming at the problem of strong distribution regularity of false targets in traditional repetitive repeater deception jamming, this paper proposes a variable pulse width smart jamming method based on intermittent chaotic sampling from the perspective of changing the amplitude and position distribution of false targets. Firstly, the mathematical model of repeater deception jamming is deduced, and the reason of strong distribution law of false targets is explored. Then, the chaotic sequence fusion method is designed, and the fusion chaotic sequence is proposed to realize the purpose of non-uniform forwarding and destroy the amplitude regularity of the false target. Finally, the range of interference energy distribution is expanded by dexterous noise convolution modulation, and the position distribution of the false target is changed. The simulation results show that compared with the traditional repeated forwarding interference, the false target distribution law of the new interference pattern proposed in this paper is obviously destroyed, and it has better interference effect.
Radar system error registration is a prerequisite and foundation for radar networking. For radars with long detection distances, their measurement errors in the detection space exhibit obvious non-uniform distribution characteristics, which causes traditional system error correction methods to be difficult to solve the error correction problem. In response to the non-uniform distribution characteristics of radar system errors, this paper proposes to divide the radar detection space into several small intervals, in each of which the system errors can be considered as a fixed value. At this time, the iterative closest point algorithm can be used to calculate the radar system error in each interval, and finally a system error compensation matrix is formed for the entire detection space, thereby achieving accurate correction of non-uniform distribution system errors. The effectiveness of the proposed method is verified by the experimental data.
For multi-platform bearings-only cross location and tracking problem in distributed multi-function sensors, a target tracking management method based on asynchronous bearing only is proposed. The distributed multi-function system requires only one integrated sensor to switch to electronic support measure (ESM) mode within each tracking cycle to update the angle measurement information of target radiation source, while the other integrated sensors still work in the original planned mode and task. Compared with traditional cross location tracking method, the proposed asynchronous bearing only tracking method can improve the capability of the distributed integrated system with multiple functions such as reconnaissance, jamming and active detection at the same time in order to cope with the complex combat environment.

Aerial imagery can provide rich geographic information. As an important ground object information, quickly and accurately extracting buildings from aerial images can achieve target monitoring, location positioning, and further enrich specific geographic information in a given area. To address the issues of segmentation result merging and irregular contour lines in semantic segmentation algorithms for building extraction, an improved model based on DeepLabv3+ for aerial building extraction is proposed by improving the feature fusion structure, constructing a comprehensive loss function, and incorporating an improved Douglas Peucker algorithm. Experimental results show that the improved model achieves an IoU of 0.794 on the test set, a 14.7% improvement compared to the original model. It effectively avoids the problem of merged segmentation between neighboring buildings and results in more regular segmentation boundaries, enabling more accurate extraction of the building contours.

It is a prerequisite to conduct the person-job matching evaluation for human resource management. The existing matching evaluation models mostly adopt the fixed weight method, and ignore the differences in the personnel structure of different units, and cannot adapt to the coarse and fine changes of the resolution granularity caused by compiled data. Therefore, a multi-granularity variable weighting evaluation model is constructed. Firstly, for the ambiguous data of resource allocation and person-job matching, the comprehensive index method is applied to extract four main factors: job position, grade, expertise, and quantity. A unit’s technological level evaluation index is proposed, classifying units into three categories: specialized efficiency-oriented, quantity scale-oriented, and hybrid models. By applying the coefficient of variation-G1 method, a variable weighting expression for the matching degree index of different unit types is formed, thus constructing a coarse-grained variable weighting evaluation model. Secondly, for fine-grained resource allocation and person-job data, considering the differences in grade, expertise, job position, and other aspects, the impact of different factors such as grade, expertise, and job position on weights is quantified. The concept of "matching deviation" is proposed and defined to comprehensively evaluate person-job matching. It leads to the construction of a fine-grained evaluation model. Finally, the evaluation under different resolution granularities is realized according to the real data. It verifies the effectiveness of the method model.
