Abstract:

A periodic fm altimeter is postulated and its illuminated area target modeled as an array of elemental scatterers. A computational form is then developed expressing the desired post mixer spectrum as a sum of spectral components corresponding to the individual scatterer returns. Application of the model is made to the case of a triangular linear sweep fm altimeter and parametric studies of the calculated post mixer spectrum presented, illustrating the effects of antenna beam geometry, target surface properties and modulation parameters.
