Radar echo state monitoring method and device

The invention discloses a radar echo state monitoring method and device. The method comprises the following steps: acquiring echo data; leading zero prediction and leading one prediction are respectively carried out on the echo data to obtain a positive sign bit number result and a negative sign bit number result; according to the number of the sign bits of the positive number and the number of the sign bits of the negative number, carrying out numerical statistics to obtain the bit width of the echo sign bits; and determining the state of the echo data according to the bit width of the echo sign bit. The data bit widths of the positive number and the negative number of the echo data are respectively judged through the leading zero and the leading one, the size of the echo data is jointly judged through the range of the positive integer and the negative integer, the reliability of the monitoring result is high, the data range is counted by adopting a method for predicting the number of sign bits, and the meth
