Paper Abstract

The protection of critical infrastructure objects such as airports, sea ports or border crossings is one of the essential security problems. In order to perform this task an electromagnetic emission passive monitoring method may be used. This is realized with distributed passive wideband radio frequency (RF) sensors utilizing the time difference of arrival (TDoA) method of electromagnetic emission source location. The complexity of the algorithms implemented in such systems requires high computational power of the signal and data processing systems. This implies the need for computational complexity reduction of implemented algorithms. In this article a computationally efficient algorithm for cross-correlation of received signals in time difference of arrival method is presented.
