Assignee: PUKYONG NATIONAL UNIVERSITY INDUSTRY-UNIVERSITY COOPERATION FOUNDATION
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 8:
9. A radar image generation apparatus comprising:
a memory configured to store instructions; and
a processor configured to execute the instructions,
wherein, when the instructions are executed by the processor, the processor is configured to receive a received signal received at each of radars that are distributed and arranged, to generate an input signal by processing the received signal, to generate a support vector that represents sparsity for sparsity modeling based on the input signal, to update the support vector, to update a coefficient corresponding to the support vector, and to generate a radar image based on the support vector and the coefficient,
wherein the processor is configured to generate a first de-ramped signal by de-ramping the received signal, to generate a second de-ramped signal by processing the first de-ramped signal, and to reformulate the second de-ramped signal based on a measurement area,
wherein the updating of the support vector comprises computing a support update matrix for updating the support vector,
wherein the computing of the support update matrix comprises initializing the support vector.
