TRACE IN MARINE RADAR :
- Once receiver receive echo from target same will be plotted on PPI.
- On PPI a bright spot is made to move in radial path from the centre of PPI to circumference of PPI.
- The visible radial line created by the moving spot from centre of PPI to circumference of PPI is called Trace.
-One TRACE is created for every pulse send out through the scanner.
- So that the number of trace create per second is equal to PRF [ Pulse repetition frequency ] .
WHILE LOOKING AT MARINE RADAR PPI AN OBSERVER CAN SEE A RADIAL LINE GOING FROM PPI CENTRE TOWARD THE CIRCUMFERENCE OF PPI , THERE ARE TRACE.
