WebGreater LFM bandwidth results in finer range resolution. Sub-meter range resolution is often required. Cross-range resolution (ΔCR) is provided by the equation: / With λ is the radar wavelength, R is the range to the scene, and LSynth as the length of the synthetic aperture or aircraft velocity (v) times the integration time (t int).

WebThis example shows how to plot a linear FM (LFM) pulse waveform. The LFM waveform has a duration of 100 microseconds, a bandwidth of 200 kHz, and a PRF of 4 kHz. Use the default values for the other properties. Compute the time-bandwidth product. Plot the real part of the waveform and plot one full pulse repetition interval. WebThe results show that the proposed method of STAP for underwater LFM with narrower modulation bandwidth can achieve a better performance in target detection and estimate, and the processing gain of STAP for CW is higher than that of LFM form 1.6dB to 5.5dB with the modulation bandwidth from 100Hz to 600Hz.
WebThe ISAR usually uses the LEM signal as the transmit signal. So, the LFM signal is adopted in the paper with the following parameters: the carrier frequency f 0, the wavelength λ 0, the chirp rate K r, the pulse repeat interval (PRI) T PRI, the pulse width T P, and the signal bandwidth satisfies B w = K r T P. The LFM signal can be expressed as Webfor an LFM bandwidth of B and a pulse width of WP T 100 s is shown in Figure 1. It will be noted that, indeed, the bandwidth is 500 MHz. If we were to process the LFM pulse using a matched filter, the impulse response of the matched filter would be 2 jtrect T t h t v t e SD W §· ¨¸ ©¹ (10 ) where we have made use of the fact that rect x
