Synthetic aperture radar (SAR) has been gradually applied to missile guidance for its advantages of all-weather, all-time and long-distance capabilities. Nevertheless, missile-borne SAR can not image on the area in front of the missile track restricted by SAR working characteristics. Missile-borne forward-looking SAR will be realized through separated transmitter and receiver. Iso-range contours, iso-Doppler contours, ground resolution and azimuth resolution are used to analyze the performance of missile-borne bistatic forward-looking SAR, as to provide the theoretical basis for its application.

The design of waveforms plays a critical role in integrated sensing and communication (ISAC) systems. An ISAC waveform with a 0dB peak‐to‐average power ratio (PAPR) is designed by combining a Golay complementary sequence with a constant envelope orthogonal frequency‐division multiplexing. By adjusting the phase modulation parameters, this waveform allows for a trade‐offs between communication and sensing capabilities. The authors focus on several key performance metrics for the proposed ISAC waveform, notably using mutual information as a holistic performance indicator to assess both sensing and communication effectiveness. Through extensive numerical simulations, the authors demonstrate that the ISAC waveform significantly enhances detection probability compared to traditional phase‐modulated waveforms. The findings suggest that this approach is beneficial for designing low PAPR phase‐modulated ISAC waveforms, enhancing both the functionality and efficiency of ISAC systems. [ABSTRACT FROM AUTHOR]
