Separation of the Target and Flares in the Trackers by using the Frequency-Domain and Time-Domain Algorithms

Authors

Abstract

The use of trackers and seeker systems has an important role in the electronic warfare. A simple and inexpensive method is based on the use of reticle devices in the trackers. But the most limitation factor for using the reticle systems is resulting from their sensitivity to false targets such as flares. There are various methods to separate the real target from flares such as dual-band detection method and blind source separation (BSS) method. In this paper, we present new algorithms of separating the real target and flares based on the BSS method. For this reason, we utilize FM reticle, and by using a beam splitter in the modified system, the main signals are extracted from the mixed signals (including the target and flare signals). The time-domain and frequency-domain algorithms are designed and compared in this approach.
