In theory the errors of measuring of co-ordinates of flight of shell-lighthouse are estimated at the use of the passive difference-phase radar system. Formulas are received for the calculation of three coordinates of shell at the use of four receiving aerials, placed as T-figure. The numeral design of relative error with the use of logarithmic method has been conducted. Dependences of this error on distance between two aerials and distance from a shell-lighthouse to base aerial in one-dimention case have been investigated. Thus frequency of radiation of radio signal was set a shell-lighthouse 433 Mhz, and absolute error of measuring of difference of phases - one degree, since achieved such accuracy. It is shown that it is here possible to attain accuracy of measuring of shell flight coordinate 0,1% at distances to it 100 m, 3000 m and 10000 m and the proper distances between receiving aerials 19,9 m, 108 m and 196 m. At the increase of measuring error to 0,5% required distance between receiving aerials goes down, accordingly, to 8,8 m, 48 m and 88 m. The use of shell-radiobeacon in the role of signaling and receiving aerial system allows to get corrections for firing from the artillery systems without the use of such active radar systems as automatic direction finder.References
