Abstract
Approximate formulas for the inband RCS of an array with series feed have been derived. The formulas are based on the hypothesis that an incident wave excites forward and backward traveling waves on the main line. The approximate formulas are in good agreement with results obtained using scattering matrices, thereby verifying the assumptions made in the approximate solution. Spikes in the RCS pattern have been identified with specific scattering sources in the array. The parameters affecting the level and location of the lobes have been noted. The main advantage of the approximate method relative to the scattering matrix method is its speed. The scattering matrix method requires that a matrix equation be solved, and its size increases with the number of array elements.
