“…Such IoOs were originally designed for broadcasting and communications. For example, PBR has used frequency modulation (FM) radio [1]- [4], amplitude modulation (AM) radio [5], digital television [6]- [9], digital audio broadcasting [10], global systems for mobile communications [11], [12], Wi-Fi [13], and satellite signals [14].…”

Recently, a range-Doppler map-based direction-of-arrival (DOA) estimation method was proposed for amplitude modulation (AM) radio-based passive bistatic radar (PBR). This method estimates the incident angle from the phase difference of the range-Doppler-bin (RD-bin) for the specific bistatic range of the cross-ambiguity function (CAF) and the Doppler frequency value rather than the phase difference between each antenna signal. In particular, in AM radio-based PBR, the RD-bin-based signal processing technique was adequately used to transform the range dimension of the CAF into an angular dimension. In this study, we improve the RD-bin-based DOA estimation method for frequency modulation (FM) radio-based PBR. The two main contributions of this paper are as follows. First, we present a criterion for deciding on the number of RD-bins using theoretical analysis. Second, we suggest that other target signals may become interference signals in the presence of multiple targets, which may degrade the DOA estimation accuracy. We also propose a least-squares-based algorithm to solve this problem. From the simulation results, we show that the proposed criterion for deciding on the number of RD-bins is appropriate for FM radio-based PBR and that the proposed least-squares algorithm successfully removes the target interferences.

This study investigates non-uniform array configurations to maximize the beamforming performance of passive coherent location (PCL) systems. The proposed array consists of eight dipole elements that are divided into two groups with different distances from the array center. This double-layered non-uniform configuration is designed considering the array antenna characteristics (peak-to-side lobe ratio, first null bandwidth, null width, and null depth). The resulting antenna array can provide more appropriate patterns for PCL systems than a conventional uniform circular array. The target detection performance of the proposed array in PCL systems is tested in a certain scenario. The results demonstrate that the proposed antenna in PCL systems can detect the target with Doppler and range errors of 1 Hz and 1.2 km, respectively, in a given situation.

“…They, however, rely on numerous simulations or experiments with various parameters or conditions [10], and thus have high cost of time, computation and software/hardware. We refer to [7], [8], [11] for more details. Even if their pertinences to specific systems or applications have been enhanced greatly, there are few opportunities to extend or transfer their achievements to other cases.…”

Evaluating the effect of blanket jamming is at the core of performance analysis and jamming/anti-jamming design for radar. Restricted to diverse jamming types and radar's applications, it is challenging to put forward a unified framework for quantitative evaluation. To address this issue, we come up with a composite evaluation by combining the robust time-frequency analysis (RTFA) and peak to average power ratio (PAPR). In term of signal-level evaluation, RTFA is exploited to analyze the echoes directly, providing the time-frequency (TF) spectrum for calculating two-dimensional image entropy. For system/application-level evaluation, we derive the variation of signal to jamming ratio (SJR) in radar processing chain, and thus define the PAPR to associate SJR with target detection, a type of common and fundamental application that usually affects the other subsequent ones. To refine composite evaluation, we modify the traditional RTFA by leveraging joint sparse model with convolution framelets to improve TF concentration and to avoid the crossing terms; meanwhile, we derive the quantitative relationship between SJR and detection probability, leading to theoretical guarantee of PAPR for evaluation. Finally, the feasibility and the superiority of the proposed evaluation approach are validated in numerical experiments.
