Multi-node small radar networking deployment based on balanced coverage

The deployment of small radar networking achieves balanced coverage, mutually compensating for blind spots at different altitude levels, which is crucial for low-altitude detection tasks. This paper establishes a complete linkage from terrain data to joint detection probability, proposes a metric for balance, and transforms the balanced coverage problem into a single-objective optimization problem under different weighted sums of traces and non-traces of autocorrelation matrices, guiding evolutionary algorithms to search for balanced solutions. Simulation experiments verify that the proposed algorithm significantly improves the balance of layered coverage and increases the median of evaluation metrics under the same experimental conditions.
