| 摘 要： | 扫描雷达的最优视频积累器因运算量大而难以实时实现.本文提出了一种新的FIR视频积累器——插值FIR积累器.与最优积累器相比,新积累器运算效率高,舍入噪声小.而且,它与最优积累器具有几乎相同的性能.因而新积累器具有较好的实用性.

| Abstract: | Requiring a large number of arithmetic operations,the optimal video integrator for scanning radars is difficult to implement in real time.A new FIR video integrator,namely interpolated FIR video integrator,is proposed.Compared with the optimal integrator,the proposed integrator is computationally efficient and has reduced roundoff noise.Moreover,the new integrator has nearly the same performances as the optimal integrator.Therefore,the proposed integrator is practical. |
