This page covers advantages and disadvantages of TWS Radar. It mentions TWS Radar advantages or benefits and TWS Radar disadvantages or drawbacks. It also describes TWS Radar basics.
What is TWS Radar?
The word TWS stands for Tracking While Scan. It is used for searching and tracking. The scanning is done using single narrow beam or with fan beam based on required scan sector.
Though it can be used to scan multiple targets, to achieve higher accuracy STT (Single Target Tracker) radar type is preferred.
TWS technique with limited scan sector is used in PAR (Precision Approach Radar) and GCA (Ground Controlled Approach) radars. These radars are used to guide aircrafts for landing. It can be replaced by ADT (Automatic Detection and Track) in modern systems.
Following are the applications of TWS radar.
• It is used in PAR and GCA radars.
• It is used for weapon control in surface to air missile systems.
