• The paper presents a digital pulse compression approach for high frequency (HF) chirp radar. The emphasis is to accomplish echo signal de-chirp operation by modified orthogonal transformation on field programmable gates array (FPGA) chip. This approach has been developed for an all-digital receiver platform which is directly radio frequency (RF) band-pass sampling, compared with the traditional analog receiver or intermediate frequency (IF) receiver, it has an easy hardware structure closing to a "soft" radar mode. The system closed-loop test shows the correctness and rationality of the design, meeting the demand of engineering application.
