  The LOFAR Two-metre Sky Survey (LoTSS) is ongoing and plans to map the
complete Northern sky in the future. The source catalogue from the public LoTSS
first data release covers 1% of the sky and is known to show some correlated
noise or fluctuations of the flux density calibration over a few degree scale.
Due to its unique and excellent design, observations from LOFAR are expected to
be an excellent opportunity to study the distribution and evolution of the
large-scale structure of the Universe in the future. We explore the LoTSS DR1
to understand the survey systematics and data quality of its very first data
release. We produce catalog mocks to determine error estimates and with our
detailed and careful analysis, we successfully recover the angular clustering
statistics of LoTSS galaxies, which fits the $\Lambda$CDM cosmology reasonably
well. We employ a Markov chain Monte Carlo (MCMC) based Bayesian analysis and
recover the best galaxy biasing scheme for LoTSS galaxies and also constrain
the radial distribution of LoTSS DR1. After masking some noisy and uneven
patches and with reasonable flux cuts, the LOFAR survey appears qualified for
large-scale cosmological studies. The upcoming data releases from LOFAR are
expected to be deeper and wider, thus will be more suitable for drawing
cosmological implications.
