Present military and aircraft radios span numerous spectial functions and needs. Modern device technology (high speed digital fft's and SAW/ACT analog chirp fourier transformers) has opened avenues for significant advances in integrated signal processing capabilities in military radios for use by the air force. Through use of this device technology, an LPI/AJ CNI integrated radio concept, is proposed for development, based upon the use of transform domain processing. Transform domain techniques allow natural combining of multi-channel synchronous/asynchronous operation, frequency hopping and discrete sequence spreading encoding, LPI functions including control of the transmitted spectrum, and networking into a single radio. As navigation and identification functions can be based upon wideband spreading sequences, these functions are inherent in system operation. Not only will the proposed concept be capable of the CNI functions, but it is capable of interoperability with present communications systems (JTIDS, GPS, and operating in present and foreseeable military and civilian networks. Electronic surveillance monitoring of the external electromagnetic environment is also inherent in the system due to the "built-in" fourier transformers.
