Abstract

The invention provides a control method and system for land feature spectrum RCS measurement. Various RCS measurement modes can be provided. The method includes the steps that a transceiver antenna is adjusted to the first target position on an arc guide rail and is controlled to point to a horizontal moving platform all the time; a tested target is adjusted to the initial position of a horizontal guide rail, and the tested target is controlled to conduct linear movement or circular movement; scattering echo data of the tested target are obtained, and RCS measurement is conducted. The system comprises a first control unit used for adjusting the transceiver antenna to the first target position on the arc guide rail and controlling the transceiver antenna to point to the horizontal moving platform all the time, a second control unit used for adjusting the tested target to the initial position of the horizontal guide rail and controlling the tested target to conduct linear movement or circular movement, and a measuring unit used for obtaining the scattering echo data of the tested target for conducting RCS measurement. The control method and system are suitable for the technical field of electromagnetic scattering feature measurement.

Description

technical field [0001] The invention relates to the technical field of electromagnetic scattering characteristic measurement, in particular to a control method and system for RCS measurement of surface object wave spectrum. Background technique [0002] Monostatic radar means that the electromagnetic wave energy is output from the radar hardware to the antenna, and then radiated (emitted) from the antenna, and then the echoes returned from one or more objects are received by the antenna that radiated energy previously, that is, the emission and reception of electromagnetic waves In the same position; dual station radar refers to the electromagnetic wave energy output from the radar hardware to the transmitting antenna, and then radiated from the transmitting antenna, and then the echo returned from one or more objects is received by the receiving antenna 21, and finally transmitted back to the hardware device of the radar , that is, the emission and reception of electromagne...
