Abstract :
A new parameter estimation algorithm based on Sub-band Dual Frequency Conjugate and LVT (SDFC-LVT) operation is proposed for fast moving targets. A new synthetic signal is constructed by the essential operations, including spectrum division, frequency shifting, and conjugate multiplications. After that, Keystone transform and LVT operator are performed on the constructed signal to attain the estimates. Since the equivalent carrier frequency is reduced greatly, the proposed method is capable of obtaining the accurate parameter estimates and resolving the problem of ambiguity which invalidates Keystone transform. It is more suitable for the situation of multiple targets. Several simulation examples demonstrate the effectiveness of the proposed method.
