By using a series of diode sampling gates and capacitive storage elements to achieve the necessary time delay, a cancellation filter is designed that will give a maximally flat passband and that will give subclutter rejection at zero frequency and at harmonics of the pulse repetition frequency. Such a filter is necessary in each range channel of moving target indication MTI radar systems. Theoretical results obtained from digital simulation are compared with actual results obtained upon completion of the filter synthesis, and a brief evaluation of the entire range channel is presented.
