“…Nevertheless, as there is no analytical expression between the objective functions and the operating points, it is difficult to obtain the exact solution to (2). Moreover, as the resource set is high dimensional, one cannot guarantee that the relationship between the objective functions and the operating points is one-to-one mapping.…”

It is well known that geometry is of significance to the performance of multistatic radars. In multistatic passive radars the receiver placement is especially critical since the transmitters of opportunity are beyond control of radar designer. Instead of considering a single objective, we suggest to implement the receiver placement by using multiobjective optimization in this paper. Specifically, three objectives with clear physical meaning are constructed. Then optimal operating points are explored through Pareto optimization. The receiver placement approach is demonstrated via a numerical example.

“…HFHSSW radar has an advancement in large-scale environment surveillance and early warning. In the recent decade, a few studies about HFHSSW radar have been conducted on system simulation (e.g., Chen, Huang, & Gill, 2016;Chen et al, 2016aChen et al, , 2016bJiang et al, 2011;Jiao et al, 2007;Li et al, 2016;Walsh et al, 2014Walsh et al, , 2015, system designation and experiment (e.g., Cui et al, 2016;Zhao et al, 2013), application in target over-the-horizon detection (see, e.g., Riddolls, 2007Riddolls, , 2008Zhang et al, 2014), and ocean surface dynamic parameters inversion (see, e.g., Ji et al, 2017;Li et al, 2017Li et al, , 2018.…”

The performance of the high-frequency hybrid sky-surface wave radar is often degraded due to the distortion of radar echoes induced by time-varying ionosphere. Here a modified S-transform method based on the direct wave for ionosphere decontamination of high-frequency hybrid sky-surface wave radar is presented. First, we extract the time-varying-ionosphere-distorted phase of the echoes from the direct wave of high-frequency hybrid sky-surface wave radar by using the modified S-transform. Then this phase function is used to decontaminate the ionosphere distortion of radar echo at each range bins. Simulations and experimental data are conducted to validate the performance of the proposed method on decontaminating the distortion. The experimental data are acquired by Wuhan Universitys ocean state measuring and analyzing radar. A mass of radar data is processed and analyzed, demonstrating that the decontamination effect is statistically significant. The method is not only effective to remove the Doppler shift of direct wave and Bragg peaks caused by ionosphere but also able to narrow the broadened direct wave and Bragg peaks. Meanwhile, the SNR is improved in most range bins; the background noise is reduced detectably, sometimes significantly; and some isolated radar echoes near direct wave or Bragg peaks are recovered or enhanced. These results indicate that the proposed decontamination algorithm works well.

Multistatic passive radars localize targets by using multiple bistatic range measurements. Multistatic localization requires all range measurements to be unbiased. It is proved by real data processing that registration is an important topic to be addressed. Traditionally, atomic clocks or GPS are used to achieve unbiased measurements. However, these approaches are unattainable under the case of multistatic passive radars as the transmitters of opportunity are beyond control. This paper proposes a novel registration method using noncooperative targets. The global convergence and accuracy of the proposed algorithm are obtained analytically. Computer simulations and experimental data are used to verify that the proposed algorithm possesses a good global convergence behavior and the performance can approach the Cramér-Rao bound (CRB).
