The relationship between the radar bandwidth and recognition ability based on the ballistic target

Reasonable bandwidth is important for a wideband ballistic missile defence radar. The relationship between bandwidth and recognition ability has great reference value. The paper analyzed the bandwidth effect on the resolution on the range profile. Then the relation between the bandwidth and the recognition accuracy rate is studied and the effect of the shape, the amount and the dimension of the targets on the relations is analyzed. Based on the HRRPs of six kinds of targets, the quantitative results are given. And the optimum bandwidth is calculated at different conditions.
