Abstract

SE DESCRIBE UN PROCESADOR DE RADAR QUE REALIZA UNA COMPENSACION DE LA ACELERACION PARA ACELERAR BLANCOS. UNA SERIE DE FILTROS SON FORMADOS QUE COMPENSAN CADA UNO DE LAS ACELERACIONES DE BLANCOS PREDETERMINADOS. LOS FILTROS OPTIMIZAN LA RELACION SEÑAL/RUIDO MEDIANTE EL SOPESADO Y COMBINACION DE LOS FILTROS DOPPLER SOBRE LOS QUE SE EXTIENDE EL BLANCO. COMO RESULTADO, SE OBTIENE UNA CAPACIDAD POTENCIADA DE DETENCION DE LOS BLANCOS DE MANIOBRA QUE EXTIENDEN SU ENERGIA SOBRE LOS FILTROS DOPPLER. SE REDUCE LA CARGA DEL PROCESADOR DEL RADAR, HACIENDO ASI PRACTICABLE LA IMPLEMENTACION DE MATRICES COHERENTES EXTENDIDAS.
