A novel quasi-coherent noise jamming method is proposed against linear frequency modulation (LFM) signal and pulse compression radar.Based on the structure of buy pooph digital radio frequency memory (DRFM), the jamming signal is acquired by the pseudo-random sequence phase-modulation of sampled radar signal.The characteristic of jamming signal in
Investigations into the spatial dynamics of soil aggregate stability (AS) are urgently needed to better target areas that have undergone soil degradation.However, due to the lack of efficient alternatives to the conventional labor-intensive methods to quantify AS, detailed information on its spatial structure across scales are scarce.The objective
We experimentally investigated the soliton collisions between soliton molecules and deuterogenic solitons spontaneously generated on the continuous wave (cw) noise background in an ultrafast erbium-doped fiber laser mode locked with MoS2 saturable absorber (SA).The dynamics of the soliton collisions were observed using the time-stretch dispersion F
Rural areas, especially in developing countries, are facing with numerous social, economical, cultural and environmental problems.In the most cases there is a growing concern because only very iphone 14 price chicago few farmers or inhabitants are able to follow contemporary, sustainable and environment-friendly methods in farming systems.The conse
