Abstract :
A tri-pole filter is proposed as a video integrator for scanning radar. Coefficients optimization of the tri-pole filter is carried out via genetic algorithm (GA) which evaluates the fitness of individual using a new function in time-domain. The tri-pole filter requires only 0.1 dB increase in signal-to-noise ratio to provide the same detection capability as the optimum integrator. Moreover, it has better stability than two-pole filter because the distance between its poles and unit circle is further. The tri-pole filter is analyzed and it is shown that its performance is superior to that of the two-pole filter.
