| Popis: | 107 In the development of radar, the radar architecture evolved from traditional mechanical radar to phased array radar. The phased array radar has the advantage of not relying on mechanical rotation to change the scanning direction, so it can greatly improve the scanning speed in phased array radar. There are three main types of phased array, passive phased array, active phased array, and digital phased array. This paper chooses digital phased array, designed and implemented based on field programmable gate array (FPGA). The digital active phased array is characterized by using the DSP (digital signal processing) to operate the phase shifting, which the signal is received and down converted by the transceiver. The advantage of using the FPGA to implement the DSP is great development flexibility. And the FPGA can precisely control any antenna element independently. The design and implementation of X-band 256 elements digital phased array radar will be discussed in detail in this paper. |
