Abstract :
Transversal digital high-pass filters are considered for extracting moving target signals from clutter. A new approach is suggested for the analytical design of clutter rejection filters. Based on the required filter pass-band response, a procedure for selecting suitable PRI (pulse repetition interval) values has been used. According to the requirements of the filter rejection-band response, a kind of high pass filter has been suggested as the prototype for determining the optimal filter weighting coefficients
