This paper proposes a new approach for the detection and location of multiple ground moving targets in the synthetic aperture radar (SAR) system. For multiple targets with various parameters in the scene with weak static clutter, it is difficult to process all the targets simultaneously, such as the estimation and compensation of Doppler frequency centroid, the estimation of Doppler chirp rate and...
The multistatic radar cross section of the stealthy objects is obvious higher than that of the monostatic radar. Using the multistatic radar based on geosynchronous/ground can improve the detecting probability of stealthy targets. Under the condition of employing space-based multistatic radar configuration, the integration and detection methods for such long dell time should deal with the problem...
In pulse compression radar system, the Keystone transform is often employed to correct the range migration, which is induced by the fact that the coherent integration time is relatively long or target echo speed is relatively high. In absence of Doppler ambiguity, the above method can be performed well, however, if the Doppler ambiguity occurs, it is usually required to resolve the ambiguous number...
High Speed Maneuvering Dim Target (HSMDT) detection is the challenging problem in pulsed monostatic airborne radar, especially under jamming and clutter conditions, the problem is not only how to remove clutter and jamming but also when we detect the HSMDT using the airborne radar the range migration and Doppler estimation problems appeared and needed to be compensated. In this paper a new hybrid...
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...
