This paper analyzes the development trend and the key to success of Penetrating Counter Air (PCA) combat in the future, focusing on the two remarkable characteristics of full platform stealth and distributed killing of PCA. Firstly, based on the organic integration and complementary advantages of two fire control modes, “target-centered all-aspect attack ”and“all-aspect attack of the launch platform” and the full-time airspace framework characterized by before/after shooting and coverage of multi-aircraft, multi-missiles and multi-targets, the concept and design principle of PCA all-domain fire field are proposed, which reflect the dynamic and comprehensive lethality performance of multi-fire nodes of coordinated air combat from a global multi-level perspective. The time-varying lethality performance model of air-to-air missiles based on the acquisition probability and its full-probability formula is redefined. Then, a single-machine fire field model and a dual-machine fire field aggregation model are established. Secondly, by introducing the three physical concepts of “gradient, divergence and curl” of field, the characterization model of space distribution, action range and deflection change characteristics of fire field are established, and the corresponding simulation and characteristic analysis of the fire field are carried out. Finally, two typical air-to-air combat tactics scenes of applying the all-domain fire field to the aiming and manipulation, single-aircraft stealth penetration and two-aircraft coordinated attack in Observe-Orient-Decide-Act (OODA) closed loop fire control are explored. It is proved that this new fire control principle possesses good technical advantages and application potential. This research plays an important role in giving full play to the performance of new weapons and equipment and effective improvement of the capability of free attack and free escape and the effectiveness of air combat. It can also provide theoretical support and technical reference for the agile construction of distributed kill net, dynamic combination of killing chain and analysis of new tactical methods for future air combat.

As the complexity of flight missions continues to increase, sending a timely warning or providing assistance to pilots helps to reduce the probability of operational errors and flight accidents. Monitoring pilots’ physiological data, real-time evaluation of mission load is a feasible technical way to achieve this. In this paper, a set of flight tasks including aircraft control, human-computer interaction and mental arithmetic tests are designed to simulate five mission loads at different flight difficulty levels. A sensitivity analysis method based on a comprehensive test is proposed to select a set of sensitive physiological factors. Then, based on the SVM hierarchical combination classification method, the pilot mission load real-time evaluation model is established. The test results show significant differences in EMG, respiration rate (abdomen), heart rate, blood oxygen saturation, pupil area, fixation duration, number of fixations, and saccades. The high accuracy obtained from experiments proved that the proposed real-time evaluation model is applicable to meet the requirements of real working environments. The findings can provide methodological references for mission load evaluation research in other fields.
