The invention provides a target searching and tracking processing method, which comprises the steps of mixing search query and tracking query into a conventional scanning wave beam layout in an insertion mode; on the basis of the existing SSR (secondary surveillance radar), by aiming at the user concerned target and the short-range target, preventing the occurrence of receiving saturation due to too strong signals received by a query machine and an answering machine through controlling the attenuation values of query signals and receiving signals so that a receiving machine of the query machine and the answering machine can still in linear logarithm amplification region in a distance from a value of being smaller than or equal to 1.85km to a value of being greater than or equal to 0.25km. Compared with the prior art, the target searching and tracking processing method has the advantages that the SSR smallest reliable monitoring distance index is improved from 1.85km to 0.25km; the target detection and tracking resolution ratio is improved; on the basis of the existing phase control array system SSR, the short-range target searching and tracking processing function can be added only through updating software; the modification is small; the cost is low.
