The integrated waveform has some impacts on radar and communication. Two aspects on communication's impact are analyzed: the limit of the modulated data and the bit error rate. The time-frequency analysis method is adopted to analyze the limit of the modulated data. After complex deduction, the bandwidth of the integrated waveform can extend when the codes are not be designed while the bandwidth will not extend with the reasonable designed codes. The bit error rate of integrated waveform is deduced based on the matched filtering in detail. The bit error rate of integrated waveform is the same as that of MSK, and this is also proved by the simulation result.

In order to improve the recognition rate under the environment with violent noise and jam, or under the condition that the data have been polluted. The authors introduce a method of recognition fusion by combining the BP neural network and the DSmT. In single sensor, after the pattern class is recognized by BP neural network, the results are transformed to DSmT generalized basic belief assignments (gbba). And then, The DSmT combination rule is adopted to fuse the outputs of all sensors. For transforming the single sensor recognition result to DSmT gbba, the authors study and present a method that by computing the Minkowski distance between the output of the waiting to be recognized pattern and the classified outputs of the samples, and then the nearnesses between them can be computed, finally the gbba of the single sensor can be gotten by normalizing the nearnesses. It is proved by experiment that the method of recognition fusion based on DSmT with BP neural network can improve the recognition rate.

This paper examines the effects of element position errors and subarray position errors on the sidelobe level of an ultra-low sidelobe array antenna with subarrays. The expressions are derived which relate the cumulative probability of sidelobe to the range of element position errors and subarray position errors. The relationship between element position errors, subarray position errors and total position errors is derived. Element position errors and subarray position errors of a two dimensional separable planar array antenna with subarrays, whose peak sidelobe is -40dB, are calculated.
