Embodiment 1
[0052] See figure 1 , figure 1 It is a flow chart of an array element-pulse code MIMO radar deceptive interference suppression method provided by an embodiment of the present invention. As shown in the figure, this method designs the coding coefficients and compensation vectors so that the false target is effectively suppressed just at the zero point of the pattern, and the main lobe deceptive interference is suppressed. In this embodiment, the main lobe deceptive Interference, that is, the jammer intercepts the radar transmission waveform and forwards it after modulation and a period of delay to form Q deceptive false targets. Among them, the real target and the false target have the same angle, but the false target and the real target have the same angle. located at different transmit pulses. Assuming that the rough estimate of the angle and distance information of the real target is known in the radar search phase (that is, the number of pulse delays of the real target); ...
