<p>PURPOSE:To obtain radio wave anti-jamming capacity having high reliability, by judging the presence of a jamming radio wave corresponding to the relative distance between a target and a projectile and determining the tracking possibility to a jamming source with the cyclicity of the jamming radio wave taken in consideration. CONSTITUTION:The power intensity of a target signal received is detected by a detector 12 while the intensity of receiving power to be received from a target inherently is calculated from the capacity of a radar apparatus itself on the basis of the distance signal from a distance tracking circuit 11. This calculated value is compared with the output of the detector 12 and the cyclicity of a jamming radio wave is detected and, when both of them coincide, the operation of the radar apparatus is set to a jamming source tracking mode. Therefore, erroneous operation due to the size of the target or circumferential environment is prevented.</p> |
