Abstract
The problem of global interpolation of numerically defined surfaces, which arises in synthesis and analysis of shaped reflector antennas, is reviewed with emphasis on the application of Pseudosplines. Several aspects of their implementation are outlined and the relative ability of pseudospline family members in accommodating the principles inherent to optical syntheses is explored.

Para aplicacoes envolvendo 0 calculo do diagrama de radiacao da antena a partir da integracao das correntes da PO induzidas sobre a superffcie refletora, como mencionado anteriormente, a principal diferenca entre interpolacoes por CPS, QPS e SPS e 0 mirnero de pontosdados utilizados pelo algoritmo de implementacao ate atingir a convergencia dos diagramas correspondentes.Nao s6 pseudosplines de ordem mais alta utilizam menos pontos como a distribuicao dos pontos utilizados pelas de ordem mais baixa (CPS) tende a uma maior concentracao nas regioes mais fortemente modeladas da superffcie
Summary
::.umerically defined surfaces, which arises in synthesis and analysis of shaped reflector antennas, is reviewed with emphasis on the application of Pseudosplines. Conforme evidenciado em [7] para refletores fortemente modelados, obtem-se a convergencia desejada para os diagramas de radiacao utilizando-se apenas urn conjunto reduzido dos pontos dados pela sfntese, a partir de urn algoritmo que permite refinamentos locais (pelo pr6prio processo de escolha daqueles pontos) em uma interpolacao global e, consequentemente, evitando os problemas observados na implementacao de series
