Radar apparatus and computer-readable storage medium
First Claim
1. A radar apparatus to detect an object by transmitting a transmission wave, comprising:
- a detecting unit configured to detect the object based on a reflected wave of the transmission wave that is reflected from the object, to output a detection result of the object;
a storage unit including a first storage part configured to store the detection result, and a second storage part configured to store a copy of information stored in the first storage part based on a copy command; and
a selecting unit configured to select one of the first storage part and the second storage part as an access destination, to output the detection result stored in one of the first storage part and the second storage part selected as the access destination,wherein the selecting unit outputs the copy command when a number of detection results stored in the first storage part exceeds a number outputtable at one transfer timing, and selects the second storage part as the access destination when the copy command is output.

Abstract
A radar apparatus to detect an object includes a detecting unit configured to detect the object based on a reflected wave received in response to transmitting a transmission wave, in order to output a detection result of the object, a storage unit including a first storage part to store the detection result, and a second storage part to store a copy of information stored in the first storage part based on a copy command, and a selecting unit configured to select one of the first storage part and the second storage part as an access destination, in order to output the detection result stored in one of the first storage part and the second storage part selected as the access destination.

4. A radar apparatus to detect an object, comprising:
-
a storage unit including a first storage part configured to successively update stored contents thereof based on a detection result that is obtained according to a radar scan, and a second storage part configured to store a copy of information stored in the first storage part based on a copy command; and an output control unit configured to copy and store a first detection result that is obtained by a first radar scan in the second storage part before stored contents of the first storage part are updated based on a second detection result that is obtained according to a second radar scan next to the first radar scan, and to read and output stored contents from one of the first storage part and the second storage part storing the first detection result during both time periods before and after the update, wherein the output control unit outputs the copy command when a number of first detection results stored in the first storage part exceeds a number outputtable at one transfer timing, and selects the second storage part as an access destination when the copy command is output. - View Dependent Claims (5, 6, 7, 8)

9. A non-transitory computer-readable storage medium having stored therein a program which, when executed by a computer of a radar apparatus, causes the computer to perform a process comprising:
-
detecting an object based on a reflected wave of a transmission wave that is transmitted from an antenna part of the radar apparatus and is reflected from the object, to output a detection result of the object; and selecting one of a first storage part configured to store the detection result, and a second storage part configured to store a copy of information stored in the first storage part based on a copy command, as an access destination, to output the detection result stored in one of the first storage part and the second storage part selected as the access destination, wherein the selecting outputs the copy command when a number of detection results stored in the first storage part exceeds a number outputtable at one transfer timing, and selects the second storage part as the access destination when the copy command is output. - View Dependent Claims (10, 11)
