摘要

This month, we start a series of columns on emitter location. The series will start with a review of the general concepts, which were originally presented in the first "EW 101" columns, starting in October 1994. Then we will cover several impor-tant emitter-location issues, such as the techniques for specifying location accuracy, the way sensitivity is measured, and the way emitter location is performed on low-probability-of-inter-cept signals. Almost every military asset must transmit signals of one kind or another in order to perform its mission. Although the asset may not be seen at night, in the presence of fog or smoke, when camouflaged, or when beyond line of sight, the location of its transmitters correspond to its physical location. Analysis of the signals transmitted from that location can usually identify the type of asset (weapon, military unit, aircraft, ship, etc.). Location and identification of the asset supports the following military activities: warning of imminent attack, threat avoidance, selection and implementation of electronic countermeasures, development of an electronic order of battle, targeting, and cueing of narrow-field-of-view reconnaissance assets.
