“…There remain few research results of the relevant countermeasures. In [4], waveform orthogonal diversity (WOD) theory is used for the suppression of active deception jamming. In addition, the multi-tone phase-modulated (MTPM) LFM signal and slopevarying (SV) LFM signal are proposed in [5].…”

According to the initial value sensitivity of chaos-based frequency modulation signals and Doppler-delay coupling characteristic of chirp signals, two kinds of orthogonal pulse diversity signals are proposed for suppressing multi-false targets jamming produced by DRFM repeat jammer in this work. With the application of self-adaption switchover of the diversity techniques, the presented method can update the strategy automatically on the basis of different DRFM modes. Besides, quantitative analysis and verification of the range-Doppler image and ECCM performance of new method are obtained through using Monte Carlo simulation and the results are proved to be consistent with theoretic analysis.

“…Extensive studies have been done on the ECCM to combat deceptive jamming, such as pulse diversity [9][10][11], motion features discrimination [12], and data fusionbased methods [13][14][15]. Nevertheless, they are not accessible for FDA, since the ECCM ability is limited into a one-dimensional view and current FDA research concentrates mainly on analyzing the range-dependent beam pattern characteristics.…”

In recent years, the frequency diverse array (FDA) radar concept has attracted extensive attention, as it may benefit from a small frequency increment, compared to the carrier frequency across the array elements and thereby achieve an array factor that is a function of the angle, the time, and the range which is superior to the conventional phase array radar (PAR). However, limited effort on the subject of FDA in electronic countermeasure scenarios, especially in the presence of mainbeam deceptive jamming, has been published. Basic FDA is not desirable for anti-jamming applications, due to the range-angle coupling response of targets. In this paper, a novel method based on subarrayed FDA signal processing is proposed to counteract deceptive ECM signals. We divide the FDA array into multiple subarrays, each of which employs a distinct frequency increment. As a result, in the subarray-based FDA, the desired target can be distinguished at subarray level in joint range-angle-Doppler domain by utilizing the fact that the jammer generates false targets with the same ranges to each subarray without reparations. The performance assessment shows that the proposed solution is effective for deceptive ECM targets suppression. The effectiveness is verified by simulation results.

“…In order to combat deception jamming, transmitting signal optimization [2], polarization characters [3], motion features [4] and DRFM quantization error [5] are used to differentiate FTs in monostatic radar. In [6,7], two identification methods of deception false targets, respectively in bistatic radar and netted radar, are presented based on data correlation algorithm using the fact that a jammer can hardly generate false target signals to each station that seem to be originated from common target sources.…”

This paper presents a discrimination method of deception false targets in multistatic radar system using signal fusion. Based on the difference in spatial scattering properties between physical targets and false targets, correlation test is used on the complex envelope sequences to identify false targets, which is formulated as a problem of likelihood ratio test in the NeymanPearson sense. The simulation results verify the efficiency of the approach to discriminate false targets on the premise of the acceptance probability of physical targets.
