Um procedimento para discriminação de alvos de radar é apresentado neste artigo. O esquema inclui um aprimoramento de dados de espalhamento ruidoso tardio com base em um algoritmo de processamento de sinal proposto e um procedimento de decisão usando filtros de aniquilação de ressonância previamente conhecidos. O estágio de processamento de sinal é especificamente adaptado para espalhar sinais e utiliza os resultados do método de expansão de singularidade. Baseia-se na reconstrução do sinal utilizando o SVD de uma matriz de dados com uma escolha adequada do número de vetores singulares empregados. Para justificar a inclusão desta etapa, mostra-se este procedimento para manter as características do sinal necessárias para identificar a resposta dispersa. Os resultados da simulação revelam claramente uma melhoria significativa devido à inclusão da etapa proposta. Esta melhoria torna-se especialmente importante quando o nível de ruído é elevado ou os alvos a serem discriminados (cinco loops poligonais regulares) têm uma geometria semelhante.

Abstract: A procedure for radar target discrimination is presented in this paper. The scheme includes an enhancement of late-time noisy scattering data based on a proposed signal processing algorithm and a decision procedure using previously known resonance annihilation filters. The signal processing stage is specifically adapted to scattering signals and makes use of the results of the singularity expansion method. It is based on a signal reconstruction using the SVD of a data matrix with a suitable choice of the number of singular vectors employed. To justify the inclusion of this stage, this procedure is shown to maintain the signal characteristics necessary to identify the scattered response. Simulation results clearly reveal a significant improvement due to the inclusion of the proposed stage. This improvement becomes especially important when the noise level is high or the targets to be discriminated (five regular polygonal loops) have a similar geometry.
