Since 1989 the Digital ESM Systems project has contributed to a higher level of understanding for ESM-techniques and direction finding in the HF-band. The capabilities of wideband digital ESM-systems to detect, analyse and locate transmissions that has formerly been considered difficult to cope with have been demonstrated both in a laboratory environment and in numerous field trials using the systems developed in the project. During the last couple of years work has been done in the area of detection and direction finding of both spread spectrum- and narrowband communications signals using TDOA (time difference of arrival) techniques. The technique can be used in a small and light system which has the potential of fitting in a UAV-concept which may prove to be an important future application.
