Abstract: This talk is given in tutorial form for the benefit of those not familiar with MIMO. The aim is to give physical insight into MIMO and its conventional equivalents. The math will be limited to the basic Fourier Transform which we all learned in undergraduate college. We will start with an explanation of MIMO and conventional arrays. It had been shown by the speaker in the past that contrary to common belief a MIMO full/thin array does not provide orders of magnitude better resolution and accuracy (10x, 100x or 1000x better) than a conventional array. Specifically, It was shown that that a conventional full/thin array can do just as well as a MIMO full/thin array. The conventional full/thin array had some grating lobes (GLs) but these were dealt with. Here a new conventional array that does not have GLs but has the SAME accuracy and resolution as the MIMO full/thin array is presented. It is a conventional thin/full array radar which is the conventional full/thin array radar with the roles of the arrays reversed, thin array transmitting and full array receiving.

It is also  shown that conventional equivalents to MIMO radar systems can do just as well as the MIMO systems in rejecting barrage-noise jammers, repeater jammers, hot-clutter jammers and main-lobe jammers. Signal processing loads, waveforms and the operation of the MIMO and its equivalents are detailed.
