Another compromise must be made between power and range. To increase the radar’s range, the power mustn’t be increased by the same factor, but by the same factor raised to the power of 4! So, to merely double the range, we must increase the power by sixteen times! Engineers then ne...
功能“POWER_APERTURE.m”实现式(1.67)给出的搜索雷达方程;如第1.10节的清单1.5所示。语法如下: PAP = power_aperture (snr, tsc, sigma, range, te, nf, loss, az_angle, el_angle) function PAP = power_aperture(snr,tsc,sigma,range,te,nf,loss,az_angle,el_angle) % This program implements Eq....
The higher the PRF, the greater the average power the radar is transmitting (assuming the peak power of each pulse is limited by the transmit circuitry) and the greater the detection range. A high or fast PRF also allows for more rapid detection and tracking of objects, as range ...

The radar-range equation, if not carefully applied, will indicate that power returned from corner-cube reflectors various as the inverse fourth power of the range. Careful attention to the meaning of each team in the equation leads to an inverse second-power relationship. This result is confirme...
In a radar, pulse droop equates to range reduction over the length of the pulse—the combination of pulse amplitude and pulse width determines the range of the radar as an integrated power level. The radar equation, as it is known, defines the trade-offs and th...

Low-band radars are also generally more power efficient when compared to higher-frequency radars of similar range. Some of the first operational radars were low-band radars. Today, advanced long-range surveillance radars include the world’s most advanced and capable airborne early warning ...
SNR versus detection range for three different values of radar peak power.img 注意,可以很容易地修改MATLAB函数“radar_eq.m”,从而求解公式(1.54),即对于给定的一组雷达参数,最大探测距离作为所需最小信噪比的函数。或者,可以修改雷达方程以计算在给定探测距离内达到一定信噪比所需的脉宽在这种情况下,雷达...
雷达的一些基本参数包括:峰值传输功率(peak Tx power)、平均传输功率(average Tx power)、雷达占空比(radar duty-cycle)、最大探测距离(maximum detection range)、距离分辨率(range bins)、距离模糊度和无模糊距离(range ambiguity and unambiguous range)、各多普勒频移参数(various Doppler shift parameters) ...
