| 摘要 | PURPOSE:To perform the stable detection of a target by suppressing the omission of the target or the judgement impossibility of a code, by adding target tracking and estimating function to the secondary radar target detecting apparatus in a radar control system. CONSTITUTION:A target detecting part 2 outputs target data consisting of information of a position, where the information of a video signal is converted to digital information, and code information. This target data is sent to a gate/ code correlation circuit 3 and used in investigating whether said target data is present in the gate of an estimated azimuth and distance calculated in a tracking part 4 and obtained from a response target ahead one scan and sent to the tracking part 4 after receiving appropriate processing. In the tracking part, the correlation of the target data and data till previous scan is taken to calculate an estimation gate for the next scan and this estimation gate is sent to a gate code correlation part 3. The target data subjected to correlation processing in the tracking part 4 is sent out from an output terminal 11 through an interface 5. | ||||||
