This work explores the relevance of multiprobe array design parameters in Planar Wide Mesh (PWM) grids for phase-referenced and reference-less scenarios. This analysis examines the behaviour of the optimisation metric as physical constraints are introduced across multiple multiprobe systems. An extensive comparison of the ideal and retrieved PWS has been conducted to assess the implications of multiprobe parameters in solving the inverse-source problem. This procedure has been repeated to retrieve the phase in a reference-less scenario that uses partially coherent observations in conjunction with PWM
grids. Results show that, in the phase-referenced scenario, the optimisation procedure overcomes the limitations introduced by multiprobe constraints. It is concluded that the PWM grids do not constrain the optimal probe spacing. Furthermore, in referenceless scenarios, our results indicate that at least four probes are required for accurate phase retrieval. In the reference-lessscenario, we find that certain probe spacing yields less accurate solutions.
