Abstract

Electronic Intelligence (ELINT) provides not only direction of arrival of intercepted signals but also provides immediate warning of threat radars, including surveillance, fire control, targeting and missile guidance systems. Radar signals from across the borders are intercepted by an ELINT receiver, recorded on a magnetic tape and are analyzed by an associated signal processing system to give a wide range of parameters, including direction, type of radar, frequency, frequency agility, Pulse Repetition Frequency (PRF), and PRF type, Scan type, Scan time and Intra pulse modulation details. These parameters are sufficient to characterize the type of emitter, and complete identification is then carried out by comparing the analyzed signal with parameters of hostile and friendly emitter characteristics stored in a library within the computer memory. Analysis of the signals and warning of a threat is virtually instantaneous and enables countermeasures of jamming and/or decoys to be initiated.

Abstract

Technological advances made in Network computing, Mobile computing, data transmissions, Sensors and integrated digital technologies for Intelligence, Surveillance and Reconnaissance have led to development of highly advanced battlefield weapons. The pace of the current and future battle is going to be so fast that there will be no time to wait for instructions and advice from the Commanding Officer. Added to this, is the complex nature of wars the defence forces are asked to handle, world over. These factors put together have revolutionized the way the wars are prosecuted. The shift clearly is towards what is commonly called as Network-Centric Warfare (NCW). This paper presents and comments on the concepts, methodologies, prevailing technologies, potential benefits and the challenges faced by NCW in modern warfare. The discussion in the paper is purely theoretical and academic in nature, with an aim to review and provide insight on this emerging field.
