Patent ID: 7847724

Claim:
A radar video data viewing system comprising: (a) a display screen for viewing multiple scans of radar video data which is generated by a seeker over a time period of four minutes to twenty minutes, wherein said multiple scans of radar video data appear on at least one graph on said display screen which allows a user to view said graph in a viewing mode which emulates real time, said multiple scans of radar video data comprising a data file having a file size of approximately four gigabytes to approximately twenty gigabytes of radar video data, said graph including: (i) a first horizontal axis having a numerical range of approximately 0 to 4096, wherein said horizontal axis represents a numerical range of radar video data samples for said multiple scans of radar video data being plotted on said graph; (ii) a first vertical axis positioned at the left end of said graph, said first vertical axis having a numerical range of approximately 0 to 127, said first vertical axis representing an amplitude for the radar video data samples being plotted on said graph; (iii) a second horizontal axis and a second vertical axis positioned below said first horizontal axis and said first vertical axis on said display screen, wherein said second vertical axis is positioned at the left end of said graph and has a numerical value of zero to one representing at least one detection gate plot for said multiple scans of radar video data; (b) a plurality of controls appearing above said graph and below said graph on said display screen for allowing said user to manipulate views of said multiple scans of radar video data appearing on said display screen and to select each of the scans of radar video data from said data file which are to appear on said display screen; (c) a plurality of text boxes appearing on said display screen below said graph, said plurality of text boxes providing an indication of a current location within the data file of the radar video data samples currently being displayed on said display screen, a start location for the data file being currently displayed on said display screen and an end location for the data file being currently displayed on said display screen; and (d) a computer software program for controlling, handling and interpreting the scans of radar video data within said data file being plotted on said graph and detection gate data for said detection gate plot, wherein said computer software program, responsive to a selection by said user of the scans of radar video data to be displayed on said display screen, plots the scans of radar video data on said display screen and plots the detection gate data on said display screen.
