A THREE-POLE ANALOG CANCELLATION FILTER WITH VARIABLE PASSBAND FOR USE IN RANGE-GATED RADARS.

Abstract

The design considerations and synthesis procedures involved in construction of a variable-passband analog cancellation filter for use in a range-gated Moving-Target-Indication (MTI) radar are presented. A three-pole Chebychev comb filter built using field-effect transistors and integrated-circuit operational amplifiers was tested and the results are compared with theoretical values. The merits of this type of filter in a range-gated radar are discussed and the performance of a complete range channel containing the filter is compared in the AN/UPS-1 air-search radar with normal radar operation using a delay-line canceller.
