Problems solved by technology

The current intermediate frequency signal processing unit mostly adopts single-channel or dual-channel ADC and DAC, which is not conducive to system miniaturization and integration; and the sampling rate of ADC and DAC chips is low, and the precision is only 12 or 14 bits; at the same time, The computing power of the signal processing chip is weak, and the data cache is small
Therefore, the current IF signal processing unit is difficult to complete multi-channel, high data rate, and computationally intensive digital phased array radar signal processing tasks

Description

technical field [0001] The invention relates to the technical field of radar, in particular to an intermediate frequency signal processing unit and a digital phased array radar having the same. Background technique [0002] Since the digital phased array radar retains all the information of the antenna array unit signal on the baseband, the digital phased array radar can use advanced digital signal processing technology to process the antenna array signal to achieve digital beamforming, target tracking and space interference. Signal is set to zero. The intermediate frequency signal processing unit is one of the core modules of the digital phased array radar. Its main function is to generate an intermediate frequency signal with a preset phase and amplitude through analog / digital conversion when the radar transmits a signal, and then transmit it to the radar's Frequency conversion and power amplification are performed on the radio frequency transceiver (T / R) module; when the...
