High range resolution with stepped FM in subapertured MIMO
This paper proposes to use stepped FM for different transmit subapertures for achieving high range resolution. Use of stepped FM for different sub-apertures provides the capability of Doppler processing and the proposed scheme is motivated by the use of stepped FM across pulses as proposed in literature. It enables Doppler processing and also partially mitigates the limitation of target velocity compensation. The paper also studies the effect of timing misalignment between subapertures and its effect on range resolution performance.
