“…Compared with simply improving the target location accuracy, the electronic counter-countermeasure (ECCM) ability of multiradar systems is of great importance for the survival and operation performance in electronic warfare. Networked radar systems using signal-fusion-based or data-fusion-based approaches to discriminate between physical targets and range deception jamming targets can be found in [10]- [14]. Some researchers even use the data fusion algorithm of a networked radar system to combat false data injection attacks when the intrusion detection is out of function [15].…”

Dual-source jamming is an effective way to prevent monopulse radar systems from performing accurate angle measurements. In this investigation, based on noncoherent dual-source jamming, we propose a cooperative deception approach, which has the benefit of causing persistent and large angular measurement errors to protect a true target and therefore can greatly reduce the discrimination capability of a distributed track-to-track radar fusion system. A scenario involving a single target accompanied by a digital radio frequency memory (DRFM)-based repeater jammer countering two radar systems is illustrated. By controlling the amplitude ratio and time delay in a statistical manner, the active decoy signal and target echo signal can form a noncoherent angular glint effect and result in the deviation of the angle tracking loop of the two radar systems from the true target in opposite directions. The track-to-track association distance related to the retransmission parameters is explicitly derived, and its statistical characteristics are analyzed in detail. Simulations verify the feasibility of the approach. The advantage of the approach lies in its ability to destroy the so-called ''common origin'' signature of the physical target by injecting false angular information. The direct result is that the true target might not successfully complete the process of track-to-track association, thereby enabling us to realize the desirable effect of ''disguise the true target and instead show false decoys''.

“…Countering DRFM-based velocity deception jamming has been one of the hottest topics in the electronic counter-countermeasures (ECCM) field. Researchers solve the problem by proposing different strategies based on pulse diversity [ 3 , 10 , 16 , 17 ], polarization [ 18 ], DRFM quantization [ 19 , 20 , 21 ], etc. Pulse diversity is commonly considered to be the most effective method to counter the DRFM-based jamming [ 3 , 10 ].…”

This paper focuses on developing an anti-velocity jamming strategy that enhances the ability of a pulse-Doppler (PD) radar to detect moving targets in the presence of translational and/or micro motion velocity jamming generated by the digital radio frequency memory (DRFM) repeat jammers. The strategy adopts random pulse initial phase (RPIP) pulses as its transmitted signal and thus gets DRFM jammers not adaptable to the randomness of initial phase of the transmitted pulses in the pulse repetition interval (PRI) domain. The difference between the true target echo and the false target jamming signal at each PRI is then utilized to recognize the true and false target signals. In particular, an entropy based multi-channel processing scheme is designed to extract the information of the received signal without the assumption that true and false targets must be both included within one coherent processing interval (CPI). Information such as the component of the received signal (target echo only, jamming only or both) or the operating manner of DRFM repeat jammer can be gained (if jamming exists). Meanwhile, we solve the false target recognition problem under sparse theory frame and our previous work named the short-time sparse recovery (STSR) algorithm is introduced to recover the motion parameters of the true and/or false targets in the time-frequency domain. It should be pointed out that both the translational false target jamming and micro motion target jamming can be recognized in our strategy. The performance of the proposed strategy is compared with the correlated processing (CP) method used by most extant strategies. It is shown that the proposed strategy can successfully recognize the existence of true and/or false targets and keep its power in recovering corresponding motion parameters even when the jamming environment is strong.

“…In practice, voltage-controlled oscillators (VCO's) are essential building blocks for both wideband radar and carrier communication systems. All practical oscillators have phase noise components, and it is well known that phase noise degrades the system performance severely if not dealt with properly [35]- [39]. Moreover, the time-varying perturbation effect of phase noise has been well investigated in extensive literature on circuit theory, circuit systems and applications since 1960's [36], [37], [40]- [45], where the Brownian motion process has been accepted as a general model to characterize and analyze the phase noise.…”

Design and Analysis of Passband Transmitted Reference Pulse Cluster UWB Systems in the Presence of Phase Noise

et al. 2018

Transmitted reference pulse cluster (TRPC) signaling was recently proposed and developed for noncoherent ultra-wideband (UWB) communications. In this paper, a practical passband TRPC-UWB system is designed and analyzed to deal with the carrier frequency offset, phase offset and phase noise inherent in voltage-controlled oscillators (VCO) of the transmitter and the receiver. Based on a general model of noisy VCO and employing some reasonable assumptions, an equivalent linear time-invariant (LTI) analytical model is obtained to facilitate the bit error rate (BER) analysis. Our analysis shows that the constant carrier frequency offset and the phase offset can be removed by employing the passband transmitter and the noncoherent receiver. Furthermore, a semi-analytical BER expression is derived to show the impact of phase noise on the system error performance. Simulation results validate the semi-analytical expressions and both of them indicate that TRPC is more robust to the effect of phase noise than conventional transmitted reference (TR) and coherent UWB Rake receivers.INDEX TERMS Bit error rate (BER) performance, phase noise, transmitted reference pulse cluster (TRPC), impulse radio, ultra-wideband (UWB).Recently, the TRPC-UWB system was further developed and improved from various practical aspects [16]- [28]. All of these research results are focused on the so-called baseband VOLUME 6, 2018
