Abstract
A horizontal plan view and a vertical side view of a weather disturbance are combined into a single axonometric display to facilitate analysis of the disturbance. Desired azimuth and elevation angles for the center of the axonometric display and which of the four quadrants of the display to be emphasized are user selectable. Either the plan view or the side view can be separately displayed in the axonometric format and the axonometric display is user selectable with the conventional display being readily available.
Claims19
A radar system axonometric display mode implementation, comprising:
- control panel means which is user operable for selecting a particular axonometric mode of operation;
- control means connected to the control panel means and responsive to the selected particular axonometric mode of operation for providing serial control data and first and second control outputs relating to the axonometric mode of operation;
- radar system antenna/transmitter/receiver (ART) means connected to the control means and responsive to the serial control data therefrom for alternately scanning a horizontal plan view and a vertical side view of a target and for transmitting serial data relating to target reflectivity for each of the horizontal plan and vertical side views;
- clock means connected to the control means and controlled by the first control output therefrom for providing first, second and third clock outputs;
- data buffer means connected to the ART means and the clock means and responsive to the first clock output for temporarily storing the target related data transmitted by the ART means;
- memory means connected to the data buffer means, the control means and the clock means and responsive to the second control output and the second clock output for storing the data temporarily stored by the data buffer means in a distance and angle format;
- first converter means connected to the memory means, and the control means and responsive to the second control output for converting the data stored by the memory means in a distance and angle format to a rectangular format;
- second converter means connected to the first converter means and the control means and responsive to the second control output for converting the data in a rectangular format to an axonometric format;
- first screen memory means connected to the second converter means, the control means and the clock means and responsive to the second control output and the third clock output for storing the data in an axonometric format;
- and
- display means connected to the screen memory means and responsive to the data stored in the axonometric format for displaying said data as an axonometric view of the target.
A method for providing a radar system axonometric display mode, comprising:
- selecting a particular axonometric mode of operation;
- providing serial control data relating to the selected axonometric mode of operation;
- transmitting the serial control data to a radar system antenna/transmitter/receiver (ART) for initiating scanning by said ART of horizontal plan and vertical side views of a target;
- transmitting serial data relating to target reflectivity for each of the horizontal plan and vertical side views;
- temporarily storing the transmitted target related data;
- storing the temporarily stored data in a distance and angle format;
- converting the data stored in a distance and angle format to a rectangular format;
- converting the data in a rectangular format to an axonometric format;
- storing the data in an axonometric format;
- and
- displaying the data in an axonometric format on a display as an axonometric view of the target.
