摘要：

Conventional monostatic SAR or DBS technology cannot realize forward-looking imaging due to Doppler symmetry ambiguity. With multiple channels in azimuth, multichannel radar can resolve the left/right ambiguity, and have the potential for forward looking imaging. However, multichannel radar have flexible channel configuration, and there are different processing schemes, which may have different imaging performance and challenges. In this papar, based on the signal model of SIMO radar, different processing schemes for multichannel radar forward-looking imaging are illustrated and simulated, as well as the corresponding potential and challenges.
