We present results on the composite supernova remnant (SNR), G327.1-1.1 whose observations were made by the SARAO MeerKAT Galactic Plane Survey, (SMGPS) at a central frequency of 1.28 GHz. MeerKAT’s high angular resolution of ~ 8’’ and high sensitivity has allowed us to produce an unprecendently detailed image of the fain SNR shell as well as the bright pulsar wind nebula (PWN) which make up this remnant. We give a summary of the observations, calibration and imaging. We discuss the radio images and integrated flux density where we observe that 38% of the radio emission comes from the PWN. From the remnant’s image we deduce that the linear size of the PWN contributes 24% to the total size of the composite remnant. Also, we discuss integrated spectral index of the PWN. We also discuss what we learn from the MeerKAT in-band spectral index of the entire remnant, shell and PWN.
