JDF And SJDF: Two DOA Estimators for Wideband Jamming
It is proved that Two-sided Correlation Transformation (TCT) algorithm is essentially a narrowband processing method. In order to locate the wideband jamming source in counter-countermeasures and electron reconnaissance domain, a new bearing finding algorithm for wideband jamming named Jamming Direction Finding (JDF) algorithm is proposed, and the Simplified JDF (SJDF) is deduced. It shows that if there is only one signal, JDF and SJDF get higher performance than TCT with theory and simulation results. It also shows that JDF is obviously better than SJDF when Signal-to-Noise Ratio (SNR) is low, but when SNR is high SJDF can performs closely to JDF. However, many signals which have non-overlapping spectra in the space, SJDF can get better performance than JDF. JDF and SJDF can be applied in counter-countermeasures and electron reconnaissance domain.
