摘要

Device simulation of radar targets with nonlinear electrical properties, which consists of N identical channels, each of which includes a series-connected broadband element receiving array antenna, an amplifier and an element transmitting antenna array, wherein the receiving and transmitting antenna arrays are lattice Van Atta, wherein that additionally introduced a storage device serially connected pre-amplifier, an amplitude detector, a quantizer-coder threshold stroystvo, pseudorandom number generator and decoder, and in each of the channels - the nonlinear transducer key block including M keys, the phase shift block comprising M phase shift devices, wherein each of the channels of the amplifier and an element transmitting antenna array are connected in series, the output memory coupled to the second input of the threshold device, the pre-amplifier input is connected to the combined output of all N elements of a receiving antenna array in each p-th channel, where an output of the receiving ant constant grating connected to the input of a nonlinear inverter, the output of which is connected to the combined first inputs of all the M key block, the second input q-th wrenches where the key unit is connected to the q-th output of the decoder, the output q-th key block key is connected to the input corresponding phase shift unit phase shifter, the output of the phase shift device M of the phase shift unit are combined and connected to the amplifier input.
