The Square Kilometre Array Observatory (SKAO) (https://www.skao.int/en), is constructing Radio Telescopes (Telescopes | SKAO), in both South Africa and in Australia, to search for Binary Pulsar’s using incredibly powerful real time processing using superior Fourier-Domain techniques.
Due to the complexity of correction of the orbital acceleration induced spectral distortion a Field Programmable Gate Array (FPGA) that performs a real time “Fourier Domain Acceleration Search” has been developed by Covnetics in collaboration with research teams at Manchester and Oxford Universities. Covnetics engineering team is working alongside this multidisciplinary science and engineering team providing the essential FPGA design skills
Covnetics have contributed to the FPGA systems architecture and systems design for the SKAO project. This FPGA is essentially a massive Digital Signal Processing (DSP) engine being fed with phase/amplitude spectral observations and performs multiple matched filter convolutions (relying on Fast Fourier (FFT) and Inverse Fast Fourier Transforms (IFFT)) to correct the acceleration induced distortion, followed by floating point harmonic summation to improve the signal to noise ratio and thus enhance the detection of distant Binary Pulsars. Each FPGA can perform 93 billion unique searches in frequency-acceleration space for each 500 second observation in real time, which equates to 46 trillion searches when scaled up for the complete telescope data centre.
