PRECISION APPROACH RADAR, PRECISION APPROACH RADAR CONTROL METHOD AND PROGRAM FOR CONTROLLING THE SAME

摘要

PROBLEM TO BE SOLVED: To stably detect an airplane subject to landing guidance.;SOLUTION: A precision approach radar executes: a step for using radar display means 30 to display approaching airplane information based on tracking target data D acquired from an ASR 40 and tracking target data E acquired from an SSR 50; a step for, when an operator selects an airplane to be guided, using a tracking management and control part 21 to calculate a predictive value and a predictive position of Doppler frequency of a target airplane that is detected by target detection means 10 based on the approaching airplane information of the selected airplane; a step for using a filter coefficient control part 14 to calculate a filter coefficient so that the calculated Doppler frequency becomes a central frequency; and a step for setting the filter coefficient calculated by the filter coefficient control part 14 to a target detection filter 11. The tracking management and control part 21 outputs a radio wave through an electronically-scanned antenna 1 that is set so that a transmission direction of the radio wave turns to a predictive position, and also receives a reflective wave of the radio wave. The target detection filter 11 extracts a target signal, which is a reflection signal of the airplane, from the received reflective wave.;COPYRIGHT: (C)2012,JPO&INPIT
