Abstract

resumo “método e dispositivo para determinar a trajetória de um projétil produzido por uma arma do tiro e localizar a posição do disparo” um dispositivo de radar (30) e um método para determinar, em uma zona de observação (10), a trajetória (20) de um projétil (1) acionado por uma pequena arma de fogo, no qual o dispositivo de radar é disposto em uma estação de radar (12) e executa uma etapa de varredura por radar da zona de observação. a etapa de varredura do radar consiste na emissão de um sinal de radar periódico (43) da freqüência (?) situado entre 4 ghz e 18 ghz, em particular, um sinal composto por dois tons que possuem respectivas frequências distintas, e demodulam e processam um sinal de retorno (44', 44") recebido em resposta ao sinal de radar, detectando, quando um tiro é disparado, uma trajetória (18', 18") do projétil compreendendo uma pluralidade de pontos ou áreas (71j). a principal característica do método é que cada ponto da trajetória é determinado pelas etapas de medição de um respectivo valor do intervalo, isto é, da distância e um respectivo valor de ângulo de azimute do projétil em relação à estação de radar, e que a etapa de recepção é realizada a uma taxa de amostragem maior do que o valor limite inferior fc,min, dependendo da freqüência ? (ghz) do sinal do radar, que pode ser expresso em khz pela fórmula fc,min=(40/3)?, e que a etapa de radar de varredura é realizada em um tempo coerente de integração (ms) estabelecido entre 10?½ e 40?½, onde ? é o comprimento de onda, expressado em metros. uma etapa é provida para calcular, a partir de vestígios da trajetória, uma linha (20) passando próxima a tais pontos da trajetória, para que esta linha pode ser assumida como a trajetória do projétil. em uma configuração exemplar, uma etapa (180) é fornecida para localizar a posição de um atirador (19) em um ponto da trajetória (20). a invenção permite identificar um projétil disparado em um tiro direto e viajando a uma velocidade sub ou supersônica, que tenha uma refletividade (rcs) menor que 1 cm2 (fig. 12a-c). 1/2 1/2
