The invention discloses a radar signal processing method and device. The processing method comprises the steps that a first node of a receiving board card receives a downlink echo signal of a radar array plane; the first node of the receiving board card distributes the downlink echo signal to a plurality of data processing board cards in a polling manner; the data processing board card distributes the received downlink echo signals to the processing nodes in a polling manner; the processing node performs data processing on the received downlink echo signal; the processing node sends the processed data to the sending board card; according to the radar signal processing method, data transmission is carried out on received downlink echo signals in an inter-board polling sending mode and an in-board polling sending mode, the received signals can be rapidly distributed to data processing nodes, meanwhile, each data processing node is provided with a complete signal processing link, and therefore the processing eff
