Abstract

PURPOSE:To accurately judge an agility cycle, by inputting the autocorrelation coefficient of an input pulse system and known radar frequency data to a judge means. CONSTITUTION:At first, the autocorrelation coefficient calculated by the k-th (k=1, 2...n) autocorrelation coefficient calculation circuit 4-k is sent to an operation circuit 6. The data calculated by the autocorrelation coefficient calculation circuit 4-1 is registered as the coefficient of a primary polynomial expression and, in the same way, the data calculated by the autocorrelation coefficient calculation circuit 4-i is successively registered as the coefficient of the i-order polynomial expression. The frequency data in the known radar of an objective radar frequency memory circuit 5 is successively sent to an operation circuit 6 as input and the operation circuit 6 calculates the value of the polynomial expression with respect to said input to send the result to a judge circuit 7. The judge circuit 7 judges that the input frequency component from the operation circuit 6 is possessed by an arrival pulse system when the operation result is received in a prescribed value or less with respect to the input from the operation circuit 6. By this method, a more accurate frequency characteristic can be drawn out within a short observation time.
