With the rapid development of the high-speed-trains (HSTs), companies are paying more and more attention on HST wireless communication system. Although some schemes have been proposed to enhance the system performance, there are still many challenges, e.g. high penetration loss, large Doppler shift, low data rate and so on. Single frequency networks (SFNs) can offer many advantages including better...
In this paper, we discussed how to use the genetic algorithm(GA) to design discrete frequency-hopping waveforms for orthogonal multistatic ISAR (inverse synthetic aperture radar). Based on the novel and creative using of GA, the optimization problem is well solved and the design results have good performance in auto-correlation and cross-correlation. The obtained results in this paper can be implemented...
The frequency-division linear frequency modulation MIMO (FDLFM-MIMO) radar is proposed in this paper, which can synthesize high-resolution range profile (HRRP) for ISAR/SAR imaging via a group of narrow-band LFM signals without over-demands on system bandwidth and sampling rate. Unfortunately, it is depicted that the HRRP sidelobes of the FDLFM-MIMO radar may be too high. According to the cause of...
