Abstract :
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.
