“…Similarly, for the whole antenna array, all the incident signals after the processes of integrate and dump can be expressed as s(t) = Ax(t) (10) where It should be noted that after the acquisition process of the satellite navigation receiver, the ranges of both the C/A code phase delay ζ and the frequency error f can be determined in (9). Specifically, ζ ∈ (−0.5, 0.5) stands for the chip of the C/A code and f is actually the Doppler frequency from the satellite to the antenna array, satisfying f ∈ (−10, 10) kHz.…”

A fast carrier phase recovery scheme is developed for satellite navigation receiver using an antenna array based on the phase retrieval theory, in which the antenna array provides sufficient measurement information for the phase recovery algorithm. First, the complex satellite signal model after coherent integration is established using the antenna array. Then, considering symbol uncertainty of the navigation data during the coherent integration time, the carrier phase estimation is formulated as a typical phase retrieval problem. At last, using the squared iterative method (SQUAREM), which is capable of superlinear convergence, a fast variant of the Wirtinger Flow (WF) algorithm is derived to solve the phase recovery problem efficiently without compromising the balance between simplicity and stability. As demonstrated by numerical results, the proposed algorithm outperforms the state-of-the-art in terms of the mean squared error (MSE) convergence. Moreover, the adjustment processes of the carrier phase in the proposed method is validated.

Digital beamforming is the holy grail of antenna array technologies, however implementing digital beamforming into practical antenna arrays has been slow due to hardware complexity and cost. We propose a relatively inexpensive new approach to digital beamforming using software defined radios. Using this system, we carried out experiments on adaptive interference cancellation. We present detailed description of the beamformer system along with the developed control software and experimentally verify the beamformer performance. Our results show that in high-interference and high-multipath environments, where carrier frequency offsets cannot be measured, conventional interference cancellation algorithms fail. We propose two new robust solutions to this problem and compare the results with multiple techniques, including the minimum variance distortionless response beamformer, which outputs the highest possible signal-to-interference-plus-noise-ratio (SINR). We experimentally demonstrate that both our approaches work well in the face of these types of signal corruptions and are capable of interference cancellation without degrading SINR or other system performance factors, and without the need for transmitter and receiver synchronization.

A Single Receive Channel DBF Method for Ultra-Wideband Radar

et al. 2019

In this paper, we present a space code agility-based single receive channel digital beamforming (DBF) method for ultra-wideband radar. The proposed single channel DBF method outperforms the existing single channel DBF method with a space-time coded array architecture regarding both the angular and the range sidelobe levels by integrating multiple pulses modulated by irrelevant space codes. A frequency-domain equivalent DBF algorithm is also developed. This algorithm is immune to the mismatch between the sampling rate of the recorded signal and the space-time response function of the space-time coded array under ultra-wideband circumstances, in which cases the existing space-time coded array DBF methods will suffer. Moreover, the target motion over multiple pulse repetition intervals (PRIs) is taken into account in the development of the frequency-domain DBF algorithm. Therefore, performance degradation due to target motion is avoided. Numerical simulations verify the effectiveness of the proposed method.
