专利汇可以提供Absolute range fuze system using limiting or agc专利检索，专利查询，专利分析的服务。并且1. An FM doppler fuze system comprising means for transmitting a signal having a carrier frequency modulated by a band of random noise, means for mixing the transmitted signal with a return echo signal modified by the doppler effect of the relative movement between the fuze and a target, low pass filter means for deriving an output adapted to actuate the fuze from the low frequency doppler portion of the output from said mixing means, and means coupled between said mixing means and said low pass filter to maintain said output proportional to the distance from said fuze to said target and independent of the size of said target.，下面是Absolute range fuze system using limiting or agc专利的具体信息内容。

权利要求

1. An FM doppler fuze system comprising means for transmitting a signal having a carrier frequency modulated by a band of random noise, means for mixing the transmitted signal with a return echo signal modified by the doppler effect of the relative movement between the fuze and a target, low pass filter means for deriving an output adapted to actuate the fuze from the low frequency doppler portion of the output from said mixing means, and means coupled between said mixing means and said low pass filter to maintain said output proportional to the distance from said fuze to said target and independent of the size of said target.

2. The fuze system comprising a white noise source adapted to produce a uniform spectrum of random frequency signals, a band pass filter operatively associated with said white noise source and adapted to pass a band of said noise, means for modulating a carrier frequency with said band of noise and transmitting a signal in the direction of the target, means adapted to mix a portion of said transmitted signal and a return echo signal from a target, low pass filter means adapted to pass the low frequency band from the output of said mixer for actuating a fuze, and means coupled between said mixing means and said low pass filter to maintain said output proportional to the distance from said fuze to said target and independent of the size of said target.
