“…This emphasises the need for good calibration. The inherent high one-way sidelobes of a MIMO radar and the problem of accurately weighting the aperture to lower these suggests MIMO is not suited for all applications, re-enforcing the conclusions drawn in [9].…”

This paper describes practical constraints on the use of MIMO radars imposed by the need for separable codes on each transmitter waveform, and where long code repetition intervals can degrade performance. This is especially problematic for long range radars with many transmitter elements which require long code repetition intervals. This causes beamforming problems if the scene is not phase stationary over this interval. Shorter codes do not help, as they introduce cross correlation which also degrades the beamforming process. We give examples of two useful orthogonal coding schemes to show how range and transmitter numbers extend the code duration and how target Doppler affects the beamforming. We describe a processing technique which will compensate for Doppler, but only if it is constant over a suitable sequence of code repetition intervals. A novel technique is then presented which virtually eliminates these problems. This uses a perimeter array with phase scanned transmitter sub arrays and a two part orthogonal MIMO code. We also identify the unique ability MIMO has to focus at all distances simultaneously in the near field.

“…The full/thin MIMO and conventional array search and waveforms are presented in [3]. If for the conventional full/thin array one chooses to receive only 4 narrow receive beams instead of 10 on each transmission, to keep the GL amplitude down as indicated in [3] then for N=10, 25 beams of width 2/N have to be transmitted instead of 10; (10N/4=2.5N=25).…”

It had originally been shown in th MIMO full/thin array radar system (consisting linear array of N elements having λ/2 spacing parallel, linear thinned receive array having equivalent to a full array of N 2 elements havin thus achieves N times the accuracy and resolutio full array of N elements, 10 times or 100 times o than a conventional array depending on N [1] shown [2] that a conventional array radar can MIMO full/thin array radar. Specifically, a con array radar was shown to provide the SAM accuracy as the MIMO array. The conventional some disadvantages relative to grating lobes th with but in some situations it could provide be efficiency than its MIMO equivalent. Here a array is presented which has the SAME accurac the MIMO full/thin array radar and has NO G Also it uses the same search time and power-ape volume search as the MIMO radar. The new consists of the same full and thin arrays bu reversed with the thin array transmitting a receiving. The new conventional array is called distinguish it from the former full/thin array. Th full/thin and thin/full MIMO and conventiona detailed on here relative to waveforms and m processing loads. The matched filter processin full/thin and thin/full arrays are dependent on w or receive beam forming is done first. Finally it MIMO radar systems do not have any adva barrage jammer, hot clutter jammer or suppression.
