A new adaptive digital beamforming of circle array on the receiving radar station based on compressed sensing is proposed. According to the sparsity of targets in space, we design a digital beamforming by using the theory of compressed sensing. This algorithm greatly reduces the number of actual array elements with the same antenna aperture. In the case of sparse array, the echo information of the...
Benefiting from its extra degrees of freedom brought by waveform diversity, MIMO radar allows to optimize the transmit beam-pattern much more freely. In this paper, a new transmit beamforming algorithm is proposed for subarray MIMO radar. Firstly, the correlation matrix of the transmitted waveforms is optimized to focus the transmit energy within the interested sectors. Then, the eigendecomposition...
The adaptive phase-only beamforming technique is very important for conventional phased array radar to suppress interference. Similar to conventional phased array radar, for the digital array radar, the adaptive phase-only beamforming technique is also very useful and can be used to enhance the radar power by making full use of transmit module microwave power of each array element. In this paper,...
