Definition of SIGINT

SIGINT is a huge sphere of operations and as you would imagine it is rather difficult to define it in a short simple statement. SIGINT can be described as all the processes and techniques required to intercept and study foreign communications and RADAR EM emissions during peacetime and in support of military operations before and during hostilities. The following is a suggested and acceptable definition:

“Sigint is the intelligence communications intelligence (comint) and electronic information derived from intelligence (elint)”
