Focusing on sensor network deployment optimization in the modern battlefield multi-sensor network deployment, from total area coverage, common view parameters of key targets, and sensor resource utilization, three aspects are used as evaluation indicators, and a multi-sensor network optimization model is designed. The fireworks algorithm is applied to the model, and the optimal solution method of the fireworks algorithm is proposed. Through the effectiveness of the simulation verification algorithm, after the fireworks calculation, the total area coverage and the common view parameters of the key areas exceed 90%, and the sensor resource utilization rate is high. The fast solving speed of the fireworks algorithm gives higher weight to the common vision parameters in key areas, which is beneficial to the increase of coverage in key areas of the battlefield.
