Abstract
An operation method of a radar signal processing apparatus in a radar system may include: generating pulse signals of a number of any one sampling rate having different phases; transmitting the pulse signals to a target; receiving reflected pulse signals reflected back from the target; generating a composite signal by sampling the reflected pulse signals and combining the sampled reflected pulse signals to match the phases; and extracting target information from the composite signal.

An operation method of a radar signal processing apparatus in a radar system, comprising the steps of:
- generating N number of basic frequency signals;
- generating pulse signals of a number of any one sampling rate having different phases by combining the N number of basic frequency signals;
- transmitting the pulse signals to a target;
- receiving reflected pulse signals reflected back from the target;
- generating a composite receive signal by sampling reflected pulse signals and combining the sampled reflected pulse signals to match the phases;
- and
- extracting target information from the composite signal,
- wherein the any one sampling rate (SR) is selected from sampling rates (sr) of actual maximum sampling frequencies (fADC_max_real) to a theoretical maximum sampling frequency (fADC_max_ideal), the any one sampling rate is a positive integer, the theoretical maximum sampling frequency is greater than the actual maximum sampling frequencies, N is the positive integer, the any one sampling rate (SR) is one of the sampling rates (sr) and the sampling rate (sr) is defined as a ratio fADC_max_ideal/fADC_max_real.
A radar signal processing apparatus, comprising:
- a processor;
- a memory in electronic communication with the processor;
- and
- instructions stored in the memory,
- wherein when the instructions are executed by the processor, the instructions cause the radar signal processing apparatus to:
- generate N number of basic frequency signals;
- generate pulse signals of a number of any one sampling rate having different phases by combining the N number of basic frequency signals;
- transmit the pulse signals to a target;
- receive reflected pulse signals reflected back from the target;
- generate a composite signal by sampling the reflected pulse signals and combining the sampled reflected pulse signals to match the phases;
- and
- extract target information from the composite signal,
- wherein the any one sampling rate (SR) is selected from sampling rates (sr) of actual maximum sampling frequencies (fADC_max_real) to a theoretical maximum sampling frequency (fADC_max_ideal), the any one sampling rate is a positive integer, the theoretical maximum sampling frequency is greater than the actual maximum sampling frequencies, N is the positive integer, the any one sampling rate (SR) is one of the sampling rates (sr) and the sampling rate (sr) is defined as a ratio fADC_max_ideal/fADC_max_real.
