Phase Shift Migration with Modified Coherent Factor Algorithm for MIMO-SAR 3D Imaging in THz Band

In multiple-input-multiple-output synthetic aperture radar (MIMO-SAR) systems, sparse arrays are usually applied, resulting in increased sidelobes of the point spread function. In this paper, a phase shift migration (PSM) imaging algorithm based on the explosion reflection model with modified coherent factor was proposed for sidelobe suppression in MIMO-SAR three-dimensional (3D) imaging application. By defining the virtual difference wavenumber, reconstructing the raw echo by data rearrangement in wavenumber domain, the original coherent factor algorithm operating in spatial domain can be achieved by the PSM algorithm frame in the wavenumber domain, which means two orders of magnitude increase in computational efficiency. The correctness of the theory is verified by simulation. Finally, a bistatic prototype imaging system in the 0.3 THz band was designed for the proof-of-principle experiments. The experimental results show that the proposed algorithm has a 0.948 structural similarity value to the original coherent factor back-projection algorithm (CF-BPA) which means comparable image quality with much superior efficiency.

STANDARDS OF NON-DISCRIMINATION IN INTERNATIONAL ECONOMIC LAW

The principle of non-discrimination constitutes a corner-stone in different fields of international economic law, notably international trade in goods and services as well as intellectual property and investment protection. While its basic rationale appears to be straightforward, the application of the different legal elements which constitute a non-discrimination obligation has proven to be most challenging. Adjudicating bodies have been applying different interpretations and standards with regard to the legal elements of ‘less favourable treatment’, ‘likeness’ and ‘regulatory purpose’, which leads to a high fragmentation of the non-discrimination principle in international economic law. This article maps out the different theories for each of these elements on the examples of WTO law, NAFTA, bilateral investment treaties (BIT) and EU law and analyses how these theories affect the scope and liberalizing effect of the non-discrimination obligation. The article then attempts to develop a coherent factor-based application of non-discrimination rules suitable for all fields of international economic law. The article submits the theory that the elements of non-discrimination should not be applied as strict legal conditions which must be proven by a complainant, but as a range of factors which are weighed and balanced by the adjudicating bodies.
