When the random pulse repetition interval (RPRI) compressed sensing radar suffers from the jamming of active velocity false target
the sparsity of target echoes will be destroyed and the RPRI compressed sensing radar's superiority on target detection and velocity measurement will be limited.In practice
due to the random modulation
the jammers can hardly update precise parameters such as the random PRI in time
which will induce the echo signals of true and false target to be sparse in different dictionaries.By utilizing this factor
a velocity false target identification algorithm is proposed within the frame of compressed sensing.The echo signals of true and false target can be sparsely presented and separated by building a joint dictionary.Also
to present application limitation of the algorithm
the autocorrelation of the joint dictionary under different RPRI signal's random mode is analyzed as well as its influence on the separation results.Computer simulation verifies the effectiveness and superiority of the algorithm.
