Abstract
This study presents the results from beampark radar observations of space debris conducted simultaneously with the EISCAT Svalbard and Tromso radars between 4.1.2018. and 5.1.2018. The measurements are processed with a new range-velocity-acceleration matched filter bank, which doubles the coherent integration time compared with the previous analysis. This has the effect of doubling the sensitivity of the measurement. The observations are correlated with the NORAD catalog, which makes it possible to validate aspects of the radar sensor model, as well as to investigate the size distribution of non-catalog objects. The beampark data is compared with the MASTER model by using a statistical radar sensor model, which evaluates the expected number of detections per day for an object, given the orbital parameters and size of the object.
