Abstract

Método de detección de blancos, por velocidad, mediante radares de alta resolución.#La presente invención se refiere a un método de detección de blancos, por velocidad, mediante radares de alta resolución que comprende las siguientes etapas:#(i) realizar la suma del valor absoluto del número de M rampas, en función de los parámetros del radar y la velocidad que se quiera detectar,#(ii) pasar por un filtro paso alto la señal integrada para eliminar el nivel de continua y otras componentes de muy baja frecuencia que la acompañan,#(iii) pasar la señal, obtenida en la etapa anterior, por un filtro paso bajo, de frecuencia de corte normalizada fc.#(iv) pasar la salida del filtro de la etapa anterior por un comparador que compara la señal con un umbral (T1) cuyo valor será el eficaz de la señal en ausencia de blanco,#(v) dividir la señal detectada como posible blanco (x{sub,filt}(k)) por la de entrada (x{sub,int}(k)).#El presente método permite proporcionar la velocidad de los blancos, independientemente del número de blancos que se encuentren en el escenario.Method of detection of targets, by speed, by means of high-resolution radars. # The present invention relates to a method of detection of targets, by speed, by means of high-resolution radars comprising the following steps: # (i) perform the sum of the absolute value of the number of M ramps, depending on the radar parameters and the speed to be detected, # (ii) pass through an integrated high pass filter to eliminate the level of continuous and other very low frequency components that accompany it, # (iii) pass the signal, obtained in the previous stage, through a low-pass filter, of normalized cutoff frequency fc. # (iv) pass the filter output of the previous stage through a comparator that compares the signal with a threshold (T1) whose value will be the effective of the signal in the absence of white, # (v) divide the detected signal as possible white (x {sub, filt} (k)) by the input (x {sub , int} (k)). # This method allows you to provide the speed of whites, regardless of the number of targets that are on stage.
