Abstract
The present invention relates to a real time radar data transmission system and process for transmitting forward error correctable data to a plurality of parallel communication channels.
Claims21
A real time radar data transmission system comprising:
- a plurality of parallel communication channels, each channel having a plurality of serially associated directional transmission elements and having one or more inputs for receiving forward error correctable data and one or more outputs for transmitting forward error correctable data;
- wherein at least one of the plurality of the directional transmission elements receives the forward error correctable data and corrects the data in error;
- and transmits the forward error correctable data to a serially associated directional transmission element;
- and wherein the data from the last of the plurality of serially associated directional transmission elements provides input to a hardware processor configured to execute instructions to utilize the forward error correctable data in a radar application;
- and wherein when an error in the data is detected a first process compares to a threshold the total number of error corrections made or attempted during a transmission of arbitrary length, and if the number of representing error corrections exceeds the threshold said first process generates a signal for resynchronizing transmission of data in real time.

A radar data transmission process comprising:
- transmitting forward error correctable data to a plurality of parallel communication channels, each channel having a plurality of serially associated directional transmission elements having one or more inputs for receiving forward error correctable data;
- receiving the forward error correctable data;
- correcting the data in error;
- transmitting the forward error correctable data to a serially associated directional transmission element;
- processing the data from the last of the plurality of serially associated directional transmission elements;
- comparing in non-real time a number of error corrections made to the data to a threshold;
- and
- if the number of corrections exceed the threshold then resynchronizing the transmitting of forward error correction data in real time.
