摘    要:针对外场雷达目标散射特性测试的需要,设计并实现了一种外场测量雷达。该雷达可在外场以频分的方式在2个固定频段上同时进行雷达散射截面的测量,以及在转台的配合下进行二维成像测试。采用脉间变频技术,避免了线形扫频方法非线性引起的问题,通过现场可编程器件的使用,可灵活设置调制脉冲和硬件距离门,最大限度地消除外场虚假信号和背景杂波的影响,可采用校准支路实时对正交解调的误差进行校准。

关 键 词:测量雷达  脉间变频  雷达散射截面  二维成像

Abstract:To meet the requirements of the field radar target scattering measurement,a 2-channel instrumentation radar based on the pulse-to-pulse frequency shifting technique was designed and realized.The radar can perform radar-cross section (RCS)measurement on two fixed frequency bands simultaneously and test the 2-demeusional imaging in cooperation with a rotation platform.The pulse-to-pulse frequency shifting technique avoided problems caused by non-linear error of the linear frequency mod- ulation method.To further eliminate the errors caused by the outdoor spurious signals and the background clutters,a series of range gate pulses generated by FPGA were set and the high resolution imaging technique was used.The quadrature errors can be correc- ted by a real-time calibration branch.The principles of the pulse-to-pulse frequency shifting were summarized,the design and real- ization were described and the test results are given and analyzed.
Keywords:instrumentation radar  pulse-to-pulse frequency shifting  RCS  2-D imaging
