Range Alignment and Motion Compensation for Missile-borne Frequency Stepped Chirp Radar
One of the difficulties for frequency stepped chirp radar (FSCR) is to resolve the range-Doppler coupling due to relative motion between the radar and the target. Motion compensation is usually adopted to solve the problem in realizing synthetic high range resolution profile (HRRP) for a moving target. For missileborne FSCR, the range migration of target echo during a coherent processing interv...
متن کاملMotion Compensation of Moving Targets for High Range Resolution Stepped-Frequency Radar
High range resolution (HRR) profiling using stepped-frequency pulse trains suffers from range shift and the attenuation/dispersion of range profiles while the target of interest is moving. To overcome these two drawbacks, a new algorithm based on the maximum likelihood (ML) estimation is proposed in this paper. Without altering the conventional stepped-frequency waveform, this algorithm can est...
متن کاملAvian Detection and Monitoring Using Frequency-stepped Chirp Signal Radar
The bird aircraft strike hazard (BASH) is a worldwide problem to aviation, which deprives lots of properties and lives every year. Avian radar systems are necessary to be developed for avian surveillance and early warning. In this paper, the frequency-stepped chirp signal radar is utilized to obtain high range resolution for micro-Doppler features extraction by means of synthetic bandwidth. The...
متن کاملStepped - Frequency Pulse Train Waveforms for Improved Radar Range
The traditional approach of improving radar range resolution using a linear frequency modulated chirp signal requires the full width of the frequency spectrum, which is not feasible in the UHF band due to interference or frequency allocation for other purposes. In this study a linear frequency modulated chirp signal is approximated using two stepped-frequency pulse train waveforms, a continuous...
متن کاملApplication of Super-sva to Stepped-chirp Radar Imaging with Frequency Band Gaps between Subchirps
It is well-known that the stepped-frequency chirp signal (SFCS) technique is one of the very effective approaches for achieving high range resolution in radar [1–5]. The SFCS is a train of subchirp pulses with up-stepped or down-stepped carrier frequencies. However, there exists a rang-Doppler coupling problem (RDCP) when applying this signal to practical radar system because longer time is nee...
