“…However, this reduces the operation time of the antenna and increases the functional costs. To overcome this issue, an in-lab test of the entire chain has been designed [5], [6] in such way that is possible to control the amplitude and phase difference of each HOM and mimic the ones that are generated from the antenna, when illuminated by the target.…”

“…Due to the working frequency and the chosen radius, TE01 is not coupled because is below cut-off. The designed tracking chain is based on the TE21 mode but a similar test can be performed also for the other configuration by satisfying the cut-off frequency condition and substitute the mode coupler to extract TM01 and TE01 modes as presented in [6] or the combination of the two degenerate TE -TE modes presented in [5].…”

Autotrack systems for space applications are typically based on monopulse. These systems require a specific test before being operative, typically through calibration towers, leading to expensive operating costs and antenna downtime. This work aims to present a technique to test in-lab these systems by the generation of high order modes as if they would be coupled using a calibration tower as well-known target. The theoretical working principle and a proof-of-concept design will be presented in Ku-band to confirm the reliability of the model.
