Abstract-An equilateral triangular microstrip antenna is proposed for circularly-polarized synthetic aperture radar (CP-SAR) systems operated in L-Band (1.27 GHz). For airborne application, a prototype antenna patch is designed, fabricated and tested. Electromagneticallycoupled, dual-feeding method is applied to generate the circularlypolarized wave radiating from the patch. The fabricated patch exhibits an axial ratio bandwidth (< 3 dB) of about 0.58% (7.4 MHz), which is consistent with the value of 0.57% (7.24 MHz) from the simulation.

“…This technique defines the reflection coefficient by the superposition method, which involves integration of all point scatterers. Summation of the point scatterers represents the whole object 2,[4][5][6][7][19][20][22][23][24][25] as shown in Eqn (1). (x, y, z) determines the integration of the point scatterers at the object or target.…”

“…A SAR image is a high-resolution map of surface target areas and terrain in the range and the azimuth dimension. Coherent SAR imaging is an alternative approach to remote sensing that provides contribution to the imaging over visible/infrared sensing technology [6][7][22][23][24][25] .…”

In this paper, a generalised target density function (TDF) is studied for active imaging by sensors such as radar. This is achieved by estimating a new TDF which is called range density function (RDF). It is proposed by utilising of a generalised range-angle density function for imaging. While the RDF is developed by a new approach based on inverse Wandermonde matrix computation, it is obtained by considering a new range and scanning angle plane different from the conventional methods.
