Filed:

Jun 3, 1985

Appl. No.:

6/740671

Inventors:

John R. Andreotti - Silver Spring MD

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

H01L 2500
H01J 4014
H03B 100

US Classification:

250332

Abstract:

A six-pole band-pass filter system and circuit configured for optimal permance in an associated infrared search and track (IRST) system which outputs data in an analog format is disclosed. The key to the successful operation of the filter is its matching to the impulse response of the associated IRST system. By adjusting certain components in the filter, it can operate as an optimal, linear, one-dimensional device to detect unresolved targets against a severely cloud-cluttered background.
