Abstract

Provided is a code allocating apparatus including an interference signal measurer configured to measure interference signals, an interference signal sharer configured to control radars to share the measured interference signals between the radars, a code allocator configured to dynamically allocate a code generated based on the measured interference signals to each of the radars, and a code applier configured to apply the code to each of the radars.

First claim

What is claimed is:

1. A code allocating apparatus comprising:
an interference signal measurer configured to measure interference signals;
an interference signal sharer configured to control radars to share the measured interference signals between the radars;
a code allocator configured to dynamically allocate a code generated based on the measured interference signals to each of the radars; and
a code applier configured to apply the code to each of the radars.

2. The apparatus of claim 1 , further comprising: a memory configured to store a code set for allocating the code.

3. The apparatus of claim 1 , wherein the interference signal sharer is configured to store the measured interference signals and allow the interference signals to be exchanged between the radars.

4. The apparatus of claim 1 , wherein the code allocator is configured to generate an objective function based on the interference signals, and the objective function is generated by allocating a weight to each of the shared interference signals.

5. The apparatus of claim 4 , wherein the code allocator is configured to select an optimal code set among pre-generated code sets using the objective function.

6. The apparatus of claim 5 , wherein the code allocator is configured to apply the optimal code set to each of the radars.

7. The apparatus of claim 1 , further comprising: a code interval adjuster configured to adjust an interval during which the code is generated, and control the interference signal measurer to measure the interference signals based on the interval during which the code is generated.

8. A code allocating method comprising:
measuring interference signals;
controlling radars to share the measured interference signals between the radars;
dynamically allocating a code generated based on the interference signals to each of the radars; and
applying the code to each of the radars.

9. The method of claim 8 , further comprising: storing a code set for allocating the code in a memory.

10. The method of claim 8 , further comprising: storing the measured interference signals and exchanging the interference signals between the radars by an interference signal sharer.

11. The method of claim 8 , further comprising:
generating an objective function based on the measured signals,
wherein the objective function is generated by allocating a weight to each of the shared interference signals.

12. The method of claim 11 , further comprising: selecting an optimal code set among pre-generated code sets using the objective function.

13. The method of claim 12 , further comprising: applying the optimal code set to each of the radars.

14. The method of claim 8 , further comprising:
adjusting an interval during which the code is generated; and
controlling an interference signal measurer to measure the interference signals based on the interval during which the code is generated.
