Use of MIMO radar to achieve multi-beam waveform tuning for SNR enhancement

It is well known that waveforms can be designed to maximize the SNR of objects with specific desired features. In some cases, it may be desirable to tune a waveform for different features at different angles. A MIMO radar can transmit multiple waveforms across a large span of angles. It is possible to design a MIMO radar waveform transmitted from individual elements to achieve the desired waveform parameters in the radar far field which is the superposition of all the individual element waveforms. A MIMO waveform model that calculates the Tx and Rx IPR across angle/range, based on the element waveforms transmitted can be used instead to calculate the element waveforms necessary to create the desired far-field waveform “beams”. The specific waveform modulation for each Tx beam can be defined. This waveform can be “tuned” to maximize the SNR of specific features.
