Abstract
Science images of the Moon and Mars are often captured with pushbroom cameras. Craters with elliptical rims are common objects of interest within the the images produced by such sensors. This work provides a framework to analyze the appearance of crater rims in pushbroom images. With knowledge of only common ellipse parameters describing the crater rim, explicit formulations are developed and shown to be convenient for drawing the apparent crater in pushbroom images. Implicit forms are also developed and indicate the orbital conditions under which craters form conics in images. Several numerical examples are provided which demonstrate how different ellipse formulations can be interpreted and used in practice.
