A Comb Filter for Use in Tracking Satellites

Abstract

The design and evaluation is presented of a 180 element comb filter. This unit was developed in conjunction with the ARPA satellite fence program for the detection and tracking of non-radiating satellites. The primary purpose of this comb filter is to detect and measure the frequency of short duration doppler signals in the presence of noise. The filter elements have a bandwidth of 10 cps and are spaced 20 cps apart to cover a 3800 cps frequency range. A multiple pen analog recorder is used to record individual filter outputs. The evaluation includes data on simulated as well as actual satellite signals.
