If the radar is operated at L-band with a wavelength of 10 cm, to achieve the same maximum micro-Doppler shift of 18.8 Hz at the same vibration rate of 15 Hz, the required displacement must be 1 cm, which may be too large in practice. Therefore, at lower radar frequency bands, the...
In the IF stage, the CWDoppler radarhas a Doppler filter bank, which is a bank ofnarrow bandfilters centered at different frequencies. The center frequencies of the filters are staggered to cover the entire range ofDoppler frequencies. TheDoppler frequencyis determined by the filter that has the...
Stepped frequency radar is a well known scheme to generate high range resolution profile(HRRP) of targets. Through appropriate radar parameter design,the radar enables both unambiguous velocity measurement and high resolution ranging within a single dwell in a high pulse repetition frequency(HPRF) mode...
