Abstract

The invention belongs to the technical field of radio frequency and relates to the improvement of a radar emission signal generation module. It includes a transmission signal generation circuit composed of a control circuit [1], a first modulator [3], an up-conversion circuit [4] and a second modulator [5], and is characterized in that: there is a clock distributor [7] ], the target distance time quantization circuit [8], the target speed time quantization circuit [9], the adder [10], the write address generation circuit [11] and the modulation pulse adjustment circuit [6] composed of dual-port RAM [12]. The present invention possesses the radar target simulator function on the basis of generating the radar emission signal, completely integrates the radar target simulator inside the radar, can realize the complete radar target simulation function, and overcomes the traditional target simulator with high cost and large volume. The disadvantages of being large and inconvenient to carry.

Description
