Interpolated FIR Video Integrator

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.
