The Terminal Approach control radar TA-10 from Thomson-CSF is an older ATC radar that has been in operation for example at Graz Airport (Austria). It was built in two variants: the TA-10MTD uses a magnetron transmitter with a pulse power of 600 kW and a maximum range of 65 NM. The version TA-10K uses a highpower klystron with a pulse power of 1900 kW and a range of 100 NM.

The letter combination TD as name annex described the filter for clutter suppression, for example MTD-900. This unit features four independent filter channels which act as a zero-velocity filter, a moving target filter (effectively a triple or quadruple canceler), and two mobile weather clutter rejection filters. The system is based on a Motorola 68020 processor.


AN/FPN-66 approach radar station consists of two Thomson-CSF equipments being provided for the US Army by Wilcox Electric Inc, a Thomson-CSF subsidiary. The two systems are this primary radar TA-10 MTD and the secondary surveillance radar RSM 970. The RSM 970 is a monopulse secondary surveillance radar which is entirely solid-state and fully compatible for Mode S.
