Abstract :
A multi-range resolution radar using sideband spectrum energy is investigated. The basic system for the multi-range resolution radar consists of a sharpening processor and least-error energy shaping filters. First, the sharpening processor makes long flat pulses sharper. Next, the least-error shaping filters compress the outputs to the desired pulse width. The output pulse width then can become narrower than the reciprocal of input bandwidth because the least-error shaping filters make the equivalent bandwidth expand by enhancing sideband spectrum energy and suppressing the main spectrum. The transmitted signals with simple phase-modulation are studied to obtain the multi-range resolution which is to be compressed to the same pulse width and another pulse width to the reciprocal of the input bandwidth. Some simulations obtain the peak-to-sidelobe level ratios after pulse compression and the improvement factors of the output signal-to-noise ratio. Experimental results are demonstrated
