Two nominal DOA estimation methods of multiple distributed sources for nested array are proposed.
- class="label">•
The proposed methods are based on difference co-array concept and they both exploit the annihilating property.
- class="label">•
Both the AF method and the AF method with SLRA can be applied to the underdetermined case where distributed sources are more than physical sensors.
- class="label">•
The proposed methods can work with unknown and different coherence loss parameters for the distributed sources.
- class="label">•
The proposed AF method with SLRA is robust to the noise.
