The AN / TPS-70 is a portable military-tactical 3D radar device with a phased array antenna . It was developed and manufactured by the American company Westinghouse Electric Corporation ( taken over by Northrop Grumman in 1996 ) as the successor to the AN / TPS-43 and is used to detect and track enemy aircraft at distances of up to 450 km.

nomenclature

The name AN ​​/ TPS-70 is based on the cross- armed forces naming system for electronic devices of the American armed forces , formerly known as the Joint Army-Navy Nomenclature System , or AN system for short. All device designations according to this system begin with "AN /". This is followed by three letters, which firstly indicate the place of installation, secondly the type of device and thirdly its purpose. In TPS, the letter T stands for "Transportable on the ground" , the P for "Radar" and the S for "Locating, bearing, searching" . The final "-70" is essentially a sequential number. AN / TPS-1 was an early radar device from World War II and AN / TPS-43 was the predecessor of the AN / TPS-70.

technology

The radar works in the S-band at 2.9 to 3.0  GHz . In contrast to the mechanically rotating parabolic antenna of the TPS-43 , it uses a rectangular and flat phased array antenna . Their dimensions (W × H) are 5.50 m by 2.54 m. It consists of 36 waveguides , each with 98 antenna slots.

The radar allows the detection and tracking of up to 500 radar targets, the distance, azimuth and altitude of which are displayed. It also features friend-foe detection ( IFF antenna above the phased array ) and clutter suppression . It is considered reliable, sensitive and accurate, and robust against attempts to disrupt ( English jamming ).
