“…As far as we know, there are no results in the literature for the relatively higher jamming signal level comparing to the RCIED activation signal. That is why wehave verified the results obtained by our simulation program comparing them to the results from [27], [28], as explained in [1].…”

The characteristics of combined and comb jamming of RCIED activation messages are presented in this paper. Combined jamming signal is formed as the sum of swept sinusoidal signal and noise signal, while comb jamming signal means that its spectrum has a number of simultaneous discrete equally distant sinusoidal components, eventually further swept. The performances of combined jamming are compared to pure sweep and pure barrage jamming. They are determined on the base of originally developed simulation program implementation. Comb jamming is analyzed based on its generation from rectangular pulse train. It is presented how the selection of ratio of pulse duration to its period and the number of frequency components in comb signal influence the obtained jamming signal characteristics. It is proved that comb jamming is especially advantageous in relation to sweep jamming when RCIED activation message duration is significantly lower than the sweep cycle period.

“…2. There are total 13 inputs to the system: 9 antenna inputs (antenna inputs [1][2][3][4][5][6][7][8][9] which should be used for signal processing in direction finding processor, 3 antenna inputs (HF connections [10][11][12] for HF connections which are forwarded to the receiving surveillance subsystem and 1 input (KLS in) for calibration signal. The antenna multicoupler switches these 13 signals towards total 8 outputs: 4 outputs (3 active and 1 reserve) to receivers devoted to signal preparation for processing in separate direction finder processor (RGOUT4-7), 3 outputs to receivers intended for spectrum surveillance (MOUT1-3) and 1 calibration output (KLSOUT).…”

“…The radio surveillance systems have very long tradition in the Institute IRITEL. IRITEL solutions in this area cover wide frequency band including HF, VHF and UHF bands separately or all together [1] - [11]. The basic equipment of these direction finding solutions are the radio signal receivers [4], [7] - [9].…”

The radio system for high frequency spectrum monitoring and signal processing used in direction finding is presented in this paper. This main function is realized using 6-channel HF radio signal receiver. The high degree of flexibility is achieved by the application of antenna multicoupler unit which allows that signals from several antennas may be processed in the system. The system signal processing especially in the demodulator is based on the most modern components of software defined radio. The system is completely developed in the Institute IRITEL applying commercial components wherever such an approach may fulfill the expected performances. The realized development is highly multidisciplinary and specific, especially HF radio signal receiver and the structure of its modules (local oscillator, RF/IF receiver subsystem, demodulator and control block) which is presented in the paper in more details. User handling is simple over intuitive user interface and system functional parameters may be easily changed. Special attention in the paper is devoted to this interface and software control procedures. The designed electrical characteristics are verified by comprehensive set of measurements according to military specifications both for HF radio signal receiver and antenna multicoupler unit and these characteristics are illustrated by several examples. The system is approved for the application in real conditions.
