track-Before-Detect(tBD) is an efficient met.od to detect dim targets for radars. Convent.onal tBD usually follows an approximate mot.on model of the target, which may cause an inaccurate integrat.on of the target energy. A tBD technique on basis of pseudo-spectrum in mixed coordinates adopting an accurate mot.on model for bistatic radar system is developed in this *** predicted posit.on in bistatic polar plane is derived according to a nonlinear funct.on that exactly describes the constant Cartesian velocity mot.on. then around the predicted posit.on, a pseudo-spectrum is formulated and its samples are accumulated to the integrat.on frame for energy integrat.on. the evolut.on of the state and the procedure of accumulat.on of the target energy are derived elaborately. the superior performance of the proposed met.od is demonstrated by some simulat.ons.

Despite of the relatively rare occurrence of alkaline igneous rocks on Earth, they are the most diverse group of igneous rocks due to variat.ons in their mineral assemblages and geochemical composit.ons. Alkaline igneous rocks are generally characterized by Si undersaturat.on, and K-Na(and in some cases C) enrichment. Alt.ough there is no unified alkaline igneous rock classificat.on scheme, diagrams such as total alkalis-Sio_(2) or K_(2)o-Sio_(2) can be used to classify alkaline igneous rocks. the origins of silica-saturated alkaline rocks(Sio_(2)>52 wt.%) are relatively complex because multiple episodes of magmatism are often involved, therefore most studies have focused on the origins of silica-undersaturated alkaline *** experimental pet.ological studies have been conducted in the past few decades. Initially, it was considered that enrichment.of trace elements was only achieved by low-degree partial melting of mantle peridotite, but the experimental melts could not reproduce the geochemical composit.on of natural alkaline igneous rocks. Subsequent studies have focused on carbonate-bearing eclogites that represent the average component.of subducted oceanic crust. Alt.ough experimental studies indicate that silica-undersaturated and alkali-oversaturated melts can be generated from eclogites, some studies have considered that natural silica-undersaturated alkaline igneous rocks are the result.of multi-stage source enrichment by incompatible elements. Low-degree partial melts of the mantle can be emplaced in the lit.ospheric mantle, forming veins consisting of phlogopite, amphibole, and pyroxene. Melting experiments including these components show that the produced melts better reproduce the naturally occurring silica-undersaturated alkaline magmas. Silica-deficient alkaline igneous rocks occur in various tectonic settings. t.ose in intraplate and divergent settings(i.e., mainly continental rifts) normally involve contribut.ons from recycled components su
